1 CALIFORNIA CONDOR ______ Arizona, California
The California Condor goes back a long way in California, to the Pleistocene epoch (approximately 1.8 million to 10,000 years ago).
Among the fauna at the Rancho la Brea tarpits, of the Pleistocene, in southern California, the California Condor seems to be the only bird surviving today.
Some say that those "California Condors", many years ago, were a different species, Gymnogyps amplus, a larger version of the present-day bird.
Gymnogyps amplus was described in 1911 from Upper Pleisocene bones from the Samwel Cave in California. It was said to be slightly larger and more robust than Gymnogyps californianus, and a direct ancestor of it.
Today, the California Condor has a wingspan of over 9 feet and a weight of up to 23 pounds, making it one of the largest birds in the world.
The transition from G. amplus to G. californianus is thought to have taken place around the very end of the Pleistocene, borne out by the difficulty had by paleontologists determining the species at that time.
Gymnogyps bones have been found in at least 25 places in the United States and Mexico.
In Arizona, at the Grand Canyon, where free-flying California Condors can again be seen now, fossil history dates back to the late Pleistocene.
Condors first appeared in the Grand Canyon fossil record more than 43,000 years ago. A perfectly intact condor skull from the late Pleistocene epoch has been found in the Stevens Cave in the Grand Canyon National Park. Radiocarbon has shown that skull to be 12,000 years old.
During the Pleistocene, the range of the California Condor formed a large u-shaped swath across North America from British Colombia south through Oregon and California to Baja California in Mexico and then east through Texas and across to Florida.
The condor bones that have been discovered in Florida are seemingly the earliest known, from the Reddick beds, dating back to the Middle Pleistocene and around 200,000 years ago, and from the Pamlico formation of the early Upper Pleistocene going back over 100,000 years. Apparently, no later condor bones from Florida have been found.
The California Condor was described to science in 1798, by the English naturalist George Shaw, who saw the bird along the coast of California.
One of the more famous early sightings of the California Condor was during the Lewis and Clark Expedition, when one was seen feeding on dead fish near the mouth of the Columbia River, in Sprague, Washington State, in November 1805.
Following a second condor found during the expedition, Captain Meriwether Lewis wrote nearly 3 pages in his journal in relation to the bird. He speculated that it was "the largest bird of North America ... it weighed 25 pounds ... (and) between the extremities of the wings, it measured 9 feet 2 inches."
By the 1940s, the range of the California Condor did not extend beyond southern California.
In Arizona, where as noted condors can be seen today, they lived, as they had for many years, until the early 1920s.
By 1982, only 22 free-ranging California Condors remained in California. The upper photograph below was taken of one of those birds in late 1981.
By 1986, only 1 female and 4 male condors roamed free. The U.S. Fish & Wildlife Service sanctioned capturing those birds and adding them to the captive breeding population. The last one was captured in April 1987,
In 1992, 63 condors existed in captivity. A few were released that year into the wild. 8 young birds were returned to California, but within a couple years, half had perished from collisions with power lines, shooting, or poisoning.
In the fall of 1996, 6 young condors were taken to a holding pen atop Vermilion Cliffs near Page, Arizona. After several weeks of feeding them stillborn calf carcasses, they were released.
From their release site, they wandered through the Monument Valley and Grand Canyon in northern Arizona, Bryce Canyon in Utah, Mesa Verde in Colorado, and as far north as Flaming Gorge in southwestern Wyoming.
Condor releases have continued about annually in northern Arizona.
In 2003, the Arizona condor population produced its first wild offspring in the Grand Canyon. A number of the birds, in that area, during the summer of 2006 traveled north to Utah to reside in hills near Zion National Park, but in the winter they returned to Arizona, where food was always available for them..
By March 2009, the number of wild-living condors in Arizona and southern Utah reached 75. In May of that year, the Peregrine Fund reported on its website that there were 358 California Condors. 189 of them were wild birds in California, Arizona, and elsewhere in the US, and in Baja California in Mexico. 169 of them were in captivity, including those in zoos, maintained for breeding purposes, or pending release.
Until recently, in Mexico, the California Condor has been classified as extirpated. In Canada, where the bird occurred in southern British Columbia, it was extirpated about two centuries ago.

is of one of the last California Condors in the wild.

2 SPOON-BILLED SANDPIPER ______ (an Asian bird, has occurred very rarely in Alaska & western Canada)
Described by Linnaeus back in 1758, the Spoon-billed Sandpiper
is now an overall
very rare species, breeding in far eastern Siberia. It winters coastally in
In North America, it has occurred very rarely in western and northern Alaska. Further south, in British Columbia, Canada, there was a record of a breeding-plumaged adult near Vancouver from July 30 to August 3, 1978.
The Spoon-billed Sandpiper was seen during one FONT Winter Japan Tour on the southern Japanese island of Amami.
The global population of the species was, not long ago, in the early 2000s, estimated as under 4,000 birds. The population at the known breeding grounds was said to be about 1,000 individuals, thus indicating a greater than 50 per recent reduction in the last decade or so.
Not only is the global population of the species declining rapidly, there is another problem: in that population, recently, there has been very little recruitment of young birds.
Although breeding success is low, it seems that the main factor in the Spoon-billed Sandpiper's decline appears to be the low rate of return to the breeding grounds.
Data collected from 2003 to 2009 on birds at Meinypilgyno (the main breeding site for the species in far-eastern, Siberian Russia), it is suggested that recruitment into the adult breeding population was effectively zero in all those years (2003 to 2009), except for 2005 & 2007.
When we first started at FONT to note the classification of the Spoon-billed Sandpiper in the 1990s it was listed as "vulnerable".
The Spoon-billed Sandpiper was uplisted to the category of "critically endangered" in 2008, when the total breeding population of the species was thought to be from 150 to 320 pairs.
In 2009-2010, the estimate was sadly revised downward to from 120 to 200 pairs.
One factor that may be responsible for the decline of the Spoon-billed Sandpiper has been the loss of resting and feeding areas along the migration flyway for the bird. There are about 8,000 kilometers of coastline between the bird's breeding grounds in Arctic Russia and its non-breeding grounds in southeast Asia. That's a long distance traveled by the bird that's about 6 inches in length.
The particular site along the coast in South Korea where the largest-ever concentration of migrating Spoon-billed Sandpipers was recorded is now the site of the world's biggest reclamation project. That habitat, vital for bird, has been lost.
Other tidal mudflats around the coast of the Yellow Sea are rapidly being lost to agriculture, industry, and urban development.
Another factor in the bird's decline is that at its wintering grounds in Myanmar (Burma) and Bangladesh, numbers of them have fallen victim to the trapping of sandpipers by hunters.
And when a population is as small as it for the Spoon-billed Sandpiper, any number lost by such practice is detrimental.
Starting in 2008, an international team of researchers has surveyed, each year in January, in Myanmar the Arakan coast and that of the Gulf of Martaban, the wintering population of Spoon-billed Sandpipers.
The coast of the Gulf of Martaban has become known as the most important wintering site for the species with about 220 birds found in 2010/2011.
Based on data from the breeding grounds, that is about half the estimated world population, and over twice as many birds as found at all the other known wintering sites put together.
Although the trapping by local hunters in Myanmar, referred to above, does not deliberately target Spoon-billed Sandpipers, they are caught as a "bycatch" in nets set for larger birds or pegged close to the mud to catch retreating fish as the tide goes out.
The 2010 survey confirmed this large-scale hunting and trapping along the Gulf of Martaban. Hunters indicated trapping up to 350 waders (or shorebirds) in a single night.
One morning in January 2010, a hunter brought the survey team a Spoon-billed Sandpiper he had caught the previous night along with about 100 Red-necked Stints.
The single Spoon-billed Sandpiper, still alive, was marked with a red flag and released by a group of local children.
That same hunter also indicated that he had last caught a Spoon-billed Sandpiper the previous August (in 2009). It was an immature bird.
Not only are young birds more likely than adults to fall victim to hunters, they are also likely to be affected disproportionately because they are thought not to return to the breeding grounds until they are two years old. Some, during that time, are speculated to spend the entire intervening year in their non-breeding area.
In September 2012, at a global meeting in Korea of biologists and other environmental scientists, a list was distributed of the "100 Most Endangered Species in the World", referring to all life, animal and plant. It was under the auspices of the International Union for Conservation of Nature, and the Zoological Society of London.
In that list, the Spoon-billed Sandpiper was positioned as number #10, making it the "most endangered bird species on Earth" in the opinion of that group, and sadly a candidate, unless something is done, for extinction.

In 2012, the conservation group SOS, "Save Our Species" was a partner in an innovative project to boost the number of juvenile Spoon-billed Sandpipers at their breeding grounds in Chukotka, in eastern Russia.
With the WWT, the "Wildfowl and Wetlands Trust", a IUCN member working with the Moscow Zoo and "Birds Russia", there was tremendous success, during the summer of that year, hatching, rearing, and releasing 9 Spoon-billed Sandpiper chicks.
Those 9 chicks were hatched from 11 eggs carefully taken from the breeding grounds on the tundra. They were monitored, hatched, and nourished in the nearby village of Meinypil'gyno before being released. The project required constant attention and effort. The fledglings gained strength living in an open-air aviary designed to shelter the birds from predators. For added protection, a guard kept vigil day and night.
The pioneering work is significant in that in the wild just 3 Spoon-billed Sandpipers out of every 20 eggs survive long enough to start their 8,000 kilometer migration to southeast Asia.
Also, as part of the project, another 20 thumbnail-sixed eggs were transported from Arctic Russia to a WWT facility in Slimbridge, England.
The first chicks were hatched there on July 4, 2012.
Of the 20 eggs that were brought to the UK, 18 chicks successfully hatched.
Those new birds were added to 12 fully-grown Spoon-billed Sandpipers that were already at the WWT center, having been brought in at the start of the conservation breeding program in November 2011.
The eggs, that were brought to England in 2012, were for more than 17 hours in flight, transported by helicopter and airplane in a journey that took, totally, 7 days to complete.
One of the eggs cracked during an airport inspection and had to be sealed using nail varnish.
When the Spoon-billed Sandpiper chicks hatched, they were about the size of a large bumblebee.
The WWT hopes that the increasing size of the captive flock of Spoon-billed Sandpipers in the UK would help trigger breeding behavior in the birds when they would later reach maturity at two years of age.

3 KITTLITZ'S MURRELET ______ Alaska
According to Birdlife International, the Kittlitz's Murrelet has recently been suffering "an extremely rapid population decline".
The species occurs in Alaska and eastern Russia. About 70 per cent of its total population is in Alaska, from Cape Lisburne south to the Aleutian Islands and east to LeConte Bay.
The Alaskan population of the Kittlitz's Murrelet is said to have fallen to as low as about 8,000 birds, with surveys indicating that the number may have declined by 80 to 90 per cent during the 15 years from 1993 to 2008.

4 COZUMEL THRASHER ______ Mexico (endemic to Cozumel Island)
In the past, the Cozumel Thrasher was fairly common on the Mexican island of Cozumel, off the northeastern coast of the Yucatan Peninsula, the only place where the bird occurs (or possibly, occurred).
If it still exists, the Cozumel Thrasher is very rare, with a tiny population, assumed to be less than 50 individuals.
The Cozumel Thrasher became so rare immediately after Hurricane Gilbert in September 1988. After that, there were only a few sightings, with even less after Hurricane Roxanne in 1995.
During surveys looking for the Cozumel Thrasher in 2004, there were 4 observations (that may have been of the same individual).
But there was another sighting observation that same year at a different site.
There was another possible sighting in 2006.
In Mexico, the Cozumel Thrasher is classified as an endangered species.

5 HORNED GUAN ______ Guatemala, Mexico
The Horned Guan lives on volcanic "islands
in the sky", occurring only on a few volcanoes in western Guatemala
and nearby Chiapas in Mexico. On those mountains, it resides in broadleaf
evergreen forest higher than 6,000 feet above sea level.
The first specimen of the beautiful, and yet odd, Horned Guan was obtained in the mid-1800s by the collector J. Quinones, supplying birds to the English aviculturist and amateur zoologist Lord Derby. It was his name of that English lord that was incorporated into the bird's scientific name, Oreophasis derbianus, done so by G.R. Gray in 1844.
That first specimen was said to have come from mountain named Volcan de Fuego in Guatemala.
And it was on that mountain where the Horned Guan was first observed "in the field" by the English ornithologist Osbert Salvin in 1861.
Over the years, very few other scientists ever saw, let alone studied, the rare bird.
In a book published in 1969, it was said that altogether only 13 scientists had ever seen Oreophasis derbianus since it was discovered.
Even to this day, not many people have actually seen the Horned Guan.
Apparently, throughout the entire 20th Century, the rare Horned Guan was never seen on Volcan de Fuego, but small numbers were found to exist on other high mountains mostly near Lake Atitlsn but also locally elsewhere in Guatemala.
Among those "other high mountains" is the Volcan Toliman, where the bird has been seen by FONT tour participants.
The global population of the Horned Guan was estimated to be less than 1,000 birds in the 1970s. It is said to have declined since then.
In Mexico, the Horned Guan is classified as an endangered species.
Below, there is a narrative describing an exciting encounter, during a FONT tour, with rare Horned Guans where they live only in remote pristine mountain forests.

THE FOLLOWING IS PART OF A NARRATIVE RELATING TO THE FONT TOUR IN GUATEMALA IN JULY 2007,
DESCRIBING A HIKE ON A MOUNTAIN DURING WHICH WE SAW THE RARE HORNED GUAN,
AND TWO OTHER BIRDS IN THIS LIST, THE AZURE-RUMPED TANAGER and the HIGHLAND GUAN,
written by Armas Hill, leader of the tour:
Extraordinary, for sure, during our FONT July '07 Guatemala tour, was July 17th.
That was the day when we looked up into the green-leaved canopy of the mountain forest above us, and saw one of the most spectacular of birds, the Horned Guan!
We had started that day early - very early in fact. We were driven, when it was still dark, by one of our two guides on the mountain, up to the dirt road until it ended. Beyond that point, it was a trail that continued to go up - and up.
The area where we were is truly a wonderful piece of Guatemalan countryside.
The forest on the slopes of the volcanic mountain is pristine.
During one of our previous Guatemala tours in that area where the dirt road ends, we saw, during a morning, 3 species of Hawk-Eagles fly overhead: the Black, the Black-and-white, and the Ornate. That alone says that the area is good for birds, with forest pristine indeed.
During our July '07 tour, as we arrived at the end of the road, it was earlier in the morning than during our previous visits.
As noted, it was still dark. Actually, there was well over an hour to go before the first light of dawn.
We looked upward to a brilliant array of stars, in a very clear sky, far away from any city lights.
The "W" of Cassiopeia was bright, and with it, a background of many stars.
The Milky Way, spread across the sky, was brilliant. In the distance, we heard the call of a Mottled Owl. We had just seen a Pauraque along the road.
Shortly after we started out on the upward trail, still in darkness, the second of our two guides pointed to a hole and a mound of loose dirt on the trail. This was the guide who lives on the mountain, and, we were told, "never left it".
And, we were told that he knows, better than anyone, the haunts and the habits of the rare and the (sorry to repeat myself) spectacular Horned Guan.
Anyway, the hole and the mound on the trail, he told us, was the workings of a Puma. "When it does poo", he said, "the animal covers it up". Yes, the area where we were was pristine, and wild!
As we walked, when still dark, we flushed a bird from its nest in an arcing branch by the trail. We soon began to hear some birds, as we experienced a wonderful dawn chorus - one quite different than what we would hear otherwise, nearly anywhere else.
The first sound we heard was the beautiful song of the Spotted Nightingale-Thrush.
A short while later, in the distance, we heard the call-note of the Spotted Wood Quail.
It's funny how the two birds named "spotted" never were - by us. We only heard them.
We did both hear and see, that day, the Ruddy-capped Nightingale-Thrush. It too has a beautiful song, as its name implies.
Motmots call early, as they contribute to the dawn chorus. As we walked, still and ever upward, we heard both the Blue-crowned Motmot (that occurs in various habitats throughout Guatemala), and the Blue-throated Motmot (that's only in the high mountains).
There was a nice assortment of Wrens that we heard at dawn, and that we later saw during daylight:
the Plain, the Gray-breasted Wood, the Spot-breasted, the Rufous-browed, and the Rufous-and-white.
Among other birds that we saw and heard in the forest that morning was a Mockingbird, called the Blue-and-white.
In addition to the Nightingale-Thrushes, others in that tribe that we encountered that morning were the White-throated Thrush and Brown-backed Solitaire.
The Rufous-browed Peppershrike was vocal, as it tends to be. We also saw a couple of its cousins that day, the Chestnut-sided Shrike-Vireo, and then later, in an area of forest on a lower slope, the Green Shrike-Vireo was present. It, too, was vocal.
In the higher forest, as we still continued upward to where we aimed to see the Horned Guan, we came across a couple brown birds of the forest, the Ruddy Foliage-gleaner, close to the ground, and the Scaly-throated Foliage-gleaner, higher in a tree. Neither stayed in view for long. Nor did the Black-throated Jay, also up in a tree. Staying around a bit longer were some Emerald Toucanets.
The Yellowish Flycatcher, an empidonax, was easy to see along our trail, as were some other birds that we encountered as they encountered some ants on which to feed.
The most-common bird in that flock, drawn to the ants was the aptly-named Common Bush Tanager.
But their supporting cast was pretty good, including the Golden-browed Warbler (a beauty), the Slate-throated Whitestart (also dapper, with whatever name - it has been called the Slate-throated Redstart), and the Tawny-throated Leaftosser, the Rufous-browed Wren, and the Chestnut-capped Brush Finch.
Also close to us, as we stopped one time for a rest, a brilliant male Violet Sabrewing, a large hummingbird (yes, very violet), sat on a low tree branch.
A little further away, in the trees, a colorful little bird, good to see, was the Blue-crowned Chlorophonia.
Larger, and also colorful, was the Collared Trogon we saw well.
Also with bright red coloration, was the male White-winged Tanager that we observed in the trees.
All of these birds were, of course, very nice, but we still had not seen THE guan. We had yet seen a guan of any kind. The Highland Guan also occurs.
The Horned Guan is not the only avian rarity that lives on the Guatemalan mountain we visited that day. There's another. It's a gem called the Azure-rumped Tanager.
For years, through most of the 20th Century, there were only just a few records of the bird. It has a limited range, at only a particular elevation, on the Pacific slope of a handful of mountains in southern Mexico and northwestern Guatemala.
There are not many of them.
But, luckily, we did encounter the rare species early in the morning, during our hike on the mountain. A pair had just recently bred in the area. After nesting, these tanagers travel about with other small forest birds in a group.
The Azure-rumped Tanager was just said to be a gem. And that it is. The bird is a mix of various blue colorations. One of those hues, the one in the bird's name, azure, is the color of the rump. The bird's crown is mauve. The bluish back is mottled with black and has a green tint. The underparts are a pale blue. The wings have turquoise.
Something else, very blue - a bright blue, was seen during our hike along the trail. On the ground, we did not know what they were at first. But, actually, they were bird droppings.
The little pieces were as brilliantly colored as the Blue Morpho butterflies that fly in the tropics. The guide, who had earlier told about the puma, said that the little bright blue pieces were droppings from the bird that we sought, the Horned Guan!
A couple hours after we saw those droppings on the trail, and after we had started our downward trek, the guides asked us, again, as they had a few times earlier, to stay still on the trail, and they wandered off into the forest.
Yes, they had done that a few times. But this time, the man who's never left the mountain, signaled to all of us to follow him into a part of the forest. We did so, and then looked up, as directed, into the trees branches.
At first, IT was rather obscured by leaves, but then we could see the form of a large turkey-like bird. Yes, it was the Horned Guan!
Actually, there were two of them there.
And, as the birds moved gently and quietly along the branches, we had wonderful looks, first by eye, then in our binoculars, and then in a telescope.
There wasn't a feature of the bird that we didn't see from the beak to the tail-tip, including the long red horn, the light-colored eye with a black eyespot, the pink legs, the white breast, and the bluish-black back.
The birds were both generally silent. One did emit a call, once, as it flew a short distance from one tree to another.
The Horned Guan is very rare. Its total population may not be much more than a thousand individuals, if that.
Like the Azure-crowned Tanager, it has a very limited range on only a handful of volcanic mountains in southern Mexico and in northwestern Guatemala.
After our extraordinary moments with the Horned Guans, we resumed our walk along the trail down the slope of the mountain. Before too long, we came across yet another guan.
This time, it was the other guan species in the area, the Highland Guan, mostly black, with a bright red throat wattle and legs. So, we were 2 for 2 with the species of guan on that part of the mountain.
During a previous tour, on a lower portion of that same mountain, we had seen Crested Guans.
There was something else bright blue that we found on the trail as we descended the mountain that afternoon on July 17, 2007.
Fruits, they were, the size and same shape as olives. The guide, who lives on the mountain, told us they were the favored food of the Horned Guan.
He called it "acetuna", which is the Spanish word for "olive". But they were not green or black. Rather, they were as a bright a blue as the Horned Guan droppings we had seen earlier that day on the trail. Their color, really, was the same.
The same color as that of the small fruits and guan droppings was also in the plumage of another bird that we saw on that Guatemalan mountain that day - the blue in the Long-tailed Manakin (below).
6 GUNNISON SAGE GROUSE ______ Colorado
The Gunnison Sage Grouse is a recently-described species (in 2001) of the USA heartland. It is very localized with a range restricted to southwest Colorado and southeast Utah. It is thought to have formerly been more widespread (possibly in New Mexico, eastern Arizona, southwest Kansas, and Oklahoma).
Now the bird occurs in 6 or 7 counties of southwest Colorado and a single county in adjacent southeast Utah.
The entire population is estimated at being less than 5,000 birds, with most (2,500-3,000) in the Gunnison Basin (of Colorado). Elsewhere populations number less than 300, with fewer than 150 in Utah.
It has disappeared from several population pockets since 1980, with an overall decline of over 60% in males attending breeding leks in the Gunnison Basin in the last 50 years.
Formerly considered a subspecies of the more-northerly Sage Grouse (now Greater Sage-Grouse), Gunnison Sage-Grouse of both sexes have plumages similar to that species, but are about 30% smaller.
7 ATLANTIC YELLOW-NOSED ALBATROSS ______ (a rarity in eastern North America, offshore & onshore)
8 BLACK-BROWED ALBATROSS ______ (a rarity in eastern North America, offshore)
Nearly 75% of the world population
of the Black-browed Albatross breed on the Falkland Islands in the South
The species also nests on South Georgia Island and on outer islands of southern Chile: Diego Raimirez, Idlefonso, Evout and Diego de Almagro.
The Black-browed Albatross is now classified as endangered, as the species has undergone a significant population decline due at least in part to long-line fisheries.

9 BERMUDA PETREL (or Cahow) ______ (a rarity in eastern North America, offshore)
10 BLACK-CAPPED PETREL ______ North Carolina, offshore
The Black-capped Petrel has a very small, fragmented, and declining breeding
range that is only on some Caribbean islands.
It is now known to nest in Haiti and the adjacent Dominican Republic, where there are an estimated 1,000 breeding pairs, mostly on the Massifs de la Selle and de la Hotte in southern Haiti.
In the Dominican Republic, where nesting occurs in the Sierra de Baoruco (Baoruco Mountains), nests are in cliffs only at a high altitude of almost 7,000 feet above sea level.
In the Lesser Antilles, small numbers have recently been recorded on Dominica, and over nearby offshore waters, suggesting that the species may nest on that island.
The bird is now believed to be extinct on Guadeloupe, where it was common in the 19th Century. It may have bred, in the past, on Martinque.
Even during the breeding season, the Black-capped Petrel is highly pelagic, occurring at that time as far from Caribbean islands as in the area of the Gulf Stream off North Carolina, USA. Birds disperse over the Caribbean Sea and Atlantic Ocean from that area (off North Carolina) to waters off northeast Brazil, but the at-sea range is said to have recently contracted.
As noted, nests are in burrows in cliffs, in montane forest, at about 1,500 to 2,300 meters (4,500 to nearly 7,000 feet) above sea level. Nesting is colonial, and begins in December.
As also noted, birds often commute long distances between breeding sites in the mountains and foraging sites at sea. When doing so, the Black-capped Petrel is primarily nocturnal and crepuscular. It feeds on fish, invertebrate swarms, fauna associated with Sargassum seaweed, and squid. Birds are attracted to localized upwellings, where the mixing of oceanic waters produces patches of the sea that are rich in nutrients.
A single Black-capped Petrel was seen during the first FONT Caribbean pelagic trip, on February 8, 1996, off the west coast of Puerto Rico. The sighting was late in the day.
And Black-capped Petrels were seen during nearly every FONT pelagic trip off the Outer Banks of North Carolina.

11 ASHY STORM PETREL ______
The global breeding population of the Ashy
Storm Petrel is essentially confined to offshore California islands: the
Farallons (75 per cent of the population) and the Channel Islands (the rest),
where there are very limited breeding opportunities in rocky crevices.
Most of these storm petrels flock together in Monterey Bay in the fall, potentially exposing the entire population to any single, possible calamity.
And of course the concentrated breeding colonies also face threats such as nest disturbance by humans and livestock, and predation by introduced mammals such as rats and cats, and depredation by gulls. These are threats to many of California's seabirds, but the Ashy Storm Petrel, being so local and geographically isolated, is especially susceptible.
In Mexican waters, the Ashy Storm Petrel has been classified as a threatened species.
12 WHOOPING CRANE ______ Nebraska, Texas
During a FONT tour in March 2014, Whooping Cranes were seen nicely at the Aransas National Wildlife Refuge in Texas.
Back in the early 1990s, on one occasion, a single Whooping Crane was seen with Sandhill Cranes during a FONT tour in the spring in Nebraska, where many Sandhill Cranes stage along the Platte River during their northward migration.

In North America, the Whooping
Crane is the rarest crane in the world, although it is not now as rare as it once was.
Since Whooping Cranes reached their low point in 1941, with only 15 recorded in Texas after the disappearance of those that had wintered nearby on the immense King Ranch, the wildlife services of the United States and Canada, working together, have brought about an amazing comeback.
In 1941, that low of 15 birds was the entire population of the species in the wild.
After a century of shooting, egg-collecting, and habitat destruction (including the drainage of Gulf Coast marshes to create rice fields), just those very few birds remained.
Recently, 2011 was a good year for the Whooping Crane, particularly so in relation to the long-established population that breeds in the Northwest Territories of Canada and winters in the Aransas area of coastal Texas.
In August of 2011, 37 Whooping Crane chicks fledged from 75 nests in the Wood Buffalo National Park in northern Alberta, Canada.
12 juvenile Whooping Cranes were captured there in August, bringing the total number of radioed birds to 23.
That, itself, is more than what the total Whooping Crane population was back in the 1940s, when only from 14 to 20 birds were dutifully reported as the number known to exist then by the Chicago Tribune.
The size of the 2010-2011 winter flock at Aransas was 283 birds.
During the winter prior to that, 2009-2010, there were 263 birds.
In 2008-2009, there were 270. In 2007-2008, 237. In 2005-2006, 220 birds.
10 captive-raised Whooping Cranes were released in February 2011 in Louisiana, where a non-migratory flock historically resided until 1950. Seven of those birds were alive seven months later.
Unfortunately, in 2011, no chicks were fledged in the wild, reintroduced Whooping Crane flocks in Florida or Wisconsin. Problems were with incubation behavior in Florida and nest abandonment in Wisconsin.
The captive Whooping Crane flocks had good production in 2011. 17 chicks were raised in captivity for the non-migratory flock in Louisiana, and 18 were headed for Wisconsin.
Including the juvenile cranes reintroduced in the fall of 2011, flock sizes were 278 in the Aransas-Wood Buffalo flock, 115 in the Wisconsin to Florida flock, 20 non-migratory birds in Florida, and 24 in Louisiana.
With also 162 cranes in captivity, the total number of Whooping Cranes at the end of 2011 was 599 birds, and that was the most in about a century!
That number resulted from years of work, of protecting and nurturing the birds.
Going back just a few years, to the summer of 2007, a record number of Whooping Crane chicks hatched that year at the Wood Buffalo National Park in Canada. An aerial survey of the breeding grounds found 65 nests and 84 new chicks. Among the chicks, there were 28 sets of twins. The previous summer, there had been 76 new chicks, including among them 24 sets of twins.
A couple years further back, in 2005, the total Whooping Crane population in North America was 470.
213 of those birds were in the self-sustaining flock that arrived that fall at Aransas in Texas.
The rest were the birds that were residents in Florida, those in captivity, and those in a flock that was re-introduced in Wisconsin and taught to migrate to Florida.
In 2005, in the Wood Buffalo National Park, 54 nesting pairs of Whooping Cranes fledged 40 chicks. Most of them were old enough to fly by mid-August, enabling them to escape predators and migrate to Texas. 33 birds of the year arrived at Aransas that winter.
And 2005 was also a good year in Texas too, as high rainfall and abundant flowing freshwater increased the number of blue crabs, the crane's favorite food (although they also eat snakes, snails, rats, and other creatures).
Historically, fossil records suggest that Whooping Cranes have existed for several million years, and once lived from the prairies of Alberta, Canada to central Mexico.
Another note from 2005: sadly 2 male Whooping Cranes were shot that year, in November, while migrating through Kansas. They were quickly discovered on the ground. One died within a week. The other had surgery to repair a broken wing, and was then flown to the Patuxent Wildlife Research Center in Maryland, where it subsequently died due to respiratory problems related to its injuries.
With a population of just a few hundred birds, even though considerably more than before, every bird matters.
In Canada and Mexico, the Whooping Crane is classified as an endangered species, but it has occurred in Mexico only very rarely.
The Whooping Crane was described to science by Linnaeus back in 1758.
An excellent book referring to cranes is entitled "The Birds of Heaven - Travels with Cranes" by Pete Matthiessen, with paintings and drawings by Robert Bateman.

13 THICK-BILLED PARROT ______ Mexico (formerly in Arizona)
In Mexico, the Thick-billed Parrot is classified as an endangered species.
14 RED-CROWNED AMAZON ______ Texas (but more so in Mexico)
In Mexico, the Red-crowned Amazon is classified as an endangered species.
15 MANGROVE HUMMINGBIRD ______ Costa Rica (endemic)
16 YELLOW-BILLED COTINGA (or ANTONIA'S COTINGA) ______ Costa Rica, Panama
In Panama, the Yellow-billed Cotinga is classified as a critically endangered species.
17 BARE-NECKED UMBRELLABIRD ______ Costa Rica, Panama
In Panama, the Bare-necked Umbrellabird has been classified as an endangered species.
18 BAHAMA SWALLOW ______ (endemic to the Bahamas, but has strayed to Florida)
19 GOLDEN-CHEEKED WARBLER ______ Guatemala, Honduras, Texas
Setophaga (formerly Dendroica) chrysoparia
In Mexico, the Golden-cheeked Warbler is classified as a threatened species. Overall, as placed in this list, it is globally classified by Birdlife International as an endangered species.
The Golden-cheeked Warbler nests only in one limited region, the "Hill Country" of Texas, making it an endemic breeder in the United States, in Texas, and, there, just in that one region in the central part of the state.
Outside the breeding season, it is in Mexico and Central America. Mostly it is in northern Central America. Although there have been some recent sightings in Costa Rica and Panama, it is very rare there.
The Golden-cheeked Warbler has been seen during FONT tours in the winter in Guatemala and Honduras, where the most have been seen in a highland forest in eastern Honduras.
In the US, the Golden-cheeked Warbler has been seen and heard during FONT tours in Texas in the area of the "Hill Country" and the Edwards Plateau, from March to May.
The bird is best located, initially, by its voice in the canopy. That is how we found it during our March 2014 FONT Texas Tour in the Lost Maples Natural Area, when we first heard it, and then saw it on March 11, the day of its first sighting of the season there, as it arrived on its nesting territory.
The Golden-cheeked Warbler nests, locally, in mature juniper and oak woodlands.
20 BLACK-CHEEKED ANT-TANAGER ______ Costa Rica (endemic)
21 AZURE-RUMPED TANAGER (or CABANIS' TANAGER) ______ Guatemala, Mexico
The Azure-rumped Tanager has a very small geographical range, only occurring locally in evergreen broadleaf mountain forest in Chiapas, Mexico and western Guatemala, generally between 1200 and 1500 meters above sea level. It has also been found in clearings with second-growth fruiting scrubs.
Until the 1970s, there were only 3 records of the species:
the type specimen in western Guatemala near Quetzaltenango from which the bird was described in 1868,
another specimen, an immature female, taken in 1937 on the mountain Ovando in Chiapas, Mexico
and another near Cacahoatan in Chiapas in 1943.
Between 1972 & 1977, there were sightings in the area of El Triunfo, in Chiapas, Mexico.
In the 1980s, the Azure-rumped Tanager was found on the slope of Sierra Madre de Chiapas in Mexico, and at a couple locations in western Guatemala.
During FONT tours in Guatemala, the Azure-rumped Tanager has been found a few places in the western part of the country, including the Pacific slope near Quetzaltenango (apparently near where the type specimen as taken over a hundred years previously), and on the slope of a volcano near Lake Atitlan near where the rare Horned Guan occurs.
The AZURE-RUMPED TANAGER is referred to in a narrative earlier in this list, relating to the HORNED GUAN (number #5 in the list).
In Mexico, the Azure-rumped Tanager has been classified as an endangered species.

22 WORTHEN'S SPARROW ______ Mexico (endemic)
The Worthen's Sparrow is now an endemic Mexican species. Only included in this North America list, as
the type specimen for the species was collected at Silver City, New Mexico in
June 1884. That bird was probably part of a small resident population that was
The species is now classified by Birdlife International as endangered. It has been classified as critically endangered.
In Mexico, the Worthen's Sparrow is classified as an endangered species.
23 HIGHLAND GUAN ______ Guatemala, Honduras
In Mexico, the Highland Guan is classified as a threatened species.
The HIGHLAND GUAN is referred to in the narrative earlier in this list, relating to the HORNED GUAN.
24 GREAT CURASSOW ______ Costa Rica, Guatemala, Panama
In Mexico, the Great Curassow is classified as a threatened species. In Panama, it is classified as vulnerable.

25 BEARDED WOOD PARTRIDGE ______ Mexico (endemic)
In Mexico, the Bearded Partridge is classified as an endangered species.
26 GREATER PRAIRIE CHICKEN ______ Colorado, Nebraska
There have historically been 3 subspecies of Greater
In the eastern United States, the subspecies T.c. cupido, called the "Heath Hen", occurred formerly in bushy habitat from Boston south to Washington. It was extirpated on the mainland about 1835. It continued to survive beyond that on the Massachusetts offshore island of Martha's Vineyard until it was last reported there in 1932. At that time, the eastern race of the Greater Prairie Chicken became extinct.
Another race of the species, in coastal Texas, is now very rare. T.c. attwateri, the "Attwater's Prairie Chicken" has declined in 30 years from 8,700 individuals in 1937 to 1,070 in 1967. After another 30 years, in 1998, only 56 individuals remained in 3 isolated populations. Even with released captive-reared birds, that subspecies is severely threatened.
The most wide-ranging of the Greater Prairie Chicken subspecies (and the one occurring in eastern Colorado and Nebraska), T.c. pinnatus, has declined over much of its range. The population in the late 1970's was estimated as 500,000. Due to its being in small isolated populations, the species overall is at considerable risk.
In Canada, the Greater Prairie Chicken has been extirpated.

27 LESSER PRAIRIE CHICKEN ______ Colorado, Kansas
The Lesser Prairie Chicken has declined substantially since the European settlement of the Great Plains. That decline is thought to be over 90% since the 19th Century, and nearly 80% since the early 1960's.
In 1980, Lesser Prairie Chickens occupied only 8% of their original range (which was historically throughout the southwest Great Plains, in southeast Colorado, southwest Kansas, western Oklahoma, northern Texas, and eastern New Mexico). Now, it is only in small, scattered populations.
The population estimate was about 50,000 birds in about 1980 (from 42,000 to 55,000 in 1979). 20 years later, in 1999, the population was estimated as 10,000 to 25,000, mostly in northwest Texas and Kansas.

28 STELLER'S EIDER ______ Alaska
In the United States, particularly Alaska, the Steller's Eider has been classified as a threatened species by the US Fish & Wildlife Service.

anywhere in the world, in Estonia,
as during the FONT tour there in April.
The SPECTACLED EIDER, Somateria fischeri (seen during FONT tours in Alaska) has until recently also been classified by Birdlife International as "vulnerable", but at least for now its status has been changed to that of "a species of least concern".
Spectacled Eiders form large wintering flocks in the Bering Sea. From aerial surveys in the 1990s, the average estimate of the number of birds in those flocks was over 300,000.
The breeding population of the Spectacled Eider in Alaska has been classified as threatened by the US Fish & Wildlife Service.
29 LONG-TAILED DUCK ______ Alaska
The Long-tailed Duck has been uplisted by Birdlife International to the "vulnerable" category due to an apparently drastic decline in the number of wintering birds in recent years, especially in the area of the Baltic Sea.
Since the early 1990s, the global population of the Long-tailed Duck has undergone a rapid decline over 3 generations, since 1993.
Outside North America, the Long-tailed Duck has been seen during FONT tours in Iceland (where they breed) and in Hokkaido, Japan (where they winter).

30 SHY ALBATROSS ______ (a rarity in western North America, offshore)
31 WANDERING ALBATROSS ______ (a rarity in western North America, offshore)
32 BLACK-FOOTED ALBATROSS ______ California, Washington State, both offshore
In Mexican waters, the Black-footed Albatross is classified as a threatened species.
33 SHORT-TAILED ALBATROSS ______ (a rarity in western North America, offshore; but now less rare)
The Short-tailed Albatross has a very small population, and a breeding range limited to 2 Japanese islands. Recent conservation efforts have resulted in a gradual population increase.
But it is one of the rarest of the world's
albatrosses, having recently flirted with extinction. It was formerly abundant
in the North Pacific, and seen even as far away from the breeding sites in Japan
as off the California coast of western North America.
The global population of the Short-tailed Albatross, or the "Aho-dori" as it is called in Japanese, following the 2006-2007 breeding season was said to be 2,364 individuals, with 1,922 birds at the principal breeding colony on Torishima Island, and 442 birds at the other more-southerly Japanese breeding colony in the Senkaku Islands.
In 1954, there were only 25 birds (including at least 6 pairs) at Torishima. In 2006, there were 426 breeding pairs on that island.
Historical information follows below relating to the albatross colonies at both Torishima and in the Senkakus.
The recent population figure given above was based upon the direct observation of breeding pairs at Torishima, along with estimates of non-breeding birds at sea and estimates of the breeding and non-breeding birds from the Senkakus (Minami-kojima).
With that population figure noted here, the likely number of mature birds is somewhere from 1,500 to 1,700 individuals.
Short-tailed Albatrosses have been seen during 2 pelagic ferry trips (as part of FONT Japan Tours) off the east coast of Honshu, once in January and once in early June.
Although the range of the bird in the Pacific is large, it seems that the Short-tailed Albatross is most apt to be seen in areas of upwelling along the shelf waters of the Pacific Rim, particularly along the coasts of Japan, eastern Russia, the Aleutians and elsewhere in Alaska.
During the breeding season (at Torishima), from December to May, the Short-tailed Albatross is in its highest density around Japan.
Satellite tracking has shown that during the post-breeding period, females spend more time offshore from Japan and Russia, while males and juveniles spend more time around the Aleutian Islands, the Bering Sea, and off the coast of North America.
Juveniles have been shown to travel about twice the distance per day and spend more time within the continental shelf than adults.

The Short-tailed Albatross has historically bred on at least 11 small Japanese islands (in the Bonin, Izu, and Ryukyu (Nansei Shoto) groups).
Away from its breeding sites, the bird has had on the open ocean, a widespread range, as noted above, from Japan east to the Bering Sea and the west coast of North America. Most of the records off Alaska, Canada, and the west coast of the mainland US have been during June-November. The species was formerly common along the western North American coast.
The Short-tailed Albatross was brought to the verge of extinction during the late 19th and early 20th Centuries by plume hunters. The feathers were used for stuffing quilts and pillows.
Another factor in the decline was habitat disturbance on islands where the birds bred, particularly on Torishima (one of the Izu Islands, 580 kilometers south of Tokyo). For years, it was only on the volcanic ash slopes of that island that the species was known to breed.
Torishima was settled by humans in 1887. Until about 1900, from 10 to 50 people lived there. The tame albatrosses were easily killed, as many as 100 to 200 a day, up to 5 million birds in 12 years. In 1902, a major volcanic eruption on the island killed many of the human inhabitants. The albatross population was severely reduced, primarily by the slaughter of the birds, and secondarily by the volcanic activity. In 1929, only about 2.000 birds remained on Torishima. People who then recolonized the island conducted what would be the last great massacre of the bird (nearly the entire remaining population of the species). By 1934, the Short-tailed Albatross was thought to be extinct.
An immature Short-tailed Albatross

Miraculously, in the early 1950's, 8 to 10
albatrosses appeared on Torishima. As immature birds, over the years,
they had been wandering the seas. During that decade, numbers varied from 20 to
In 1958, on Torishima, there were only 14 or 15 adults, 5 to 7 immatures, and 8 chicks.
Since then, there's been a slow but steady increase in the population of the bird, with Torishima, most of the time, the only known breeding location for the species in the world.
In 1960, all of the chicks (6 of them) were found
killed. Only 22 adult birds were found. But during the 1960's, the population
began to rise more substantially to over 50 birds.
In the 1970's it was to over 60. By 1979, the count was 95 birds (& 22 chicks).
In March 1981, there were about 130 birds (& 34 chicks). In November 1981, 63 eggs were found. In March 1982, there 21 chicks with about 140 adults and subadults.
The total population figures following 1979 were based on observations at Torishima together with estimates of non-breeders away from the colony. Thus, in 1982, the world population of the species was said to be about 250 birds. Since 1979, over 50 eggs have been laid annually.
In 1991, the Short-tailed Albatross population
had risen to about 500 birds. Since then it has increased further. The rate of
increase has been about 7% per year. Thus, the population doubled in 10 years.
Breeding success improved with grass transplantation to stabilize nesting areas.
Still, however, the population remained rather vulnerable due to the volcanic
nature of Torishima.
In 2008, ten Short-tailed Albatross chicks were moved by helicopter from Torishima to another island, Mukojima, about 350 kilometers to the southeast in the western Pacific Ocean.
Mukojima, in the Bonin Island group, was a site of a former Short-tailed Albatross colony. Birds bred there until the 1920s. Mukojima is non-volcanic.
At Torishima, 80 to 85 per cent of the world population of the Short-tailed Albatross nest on a highly erodible slope on an outwash plain from the caldera of an active volcano.
Monsoons send torrents of ash-laden water down the slope across the colony site.
A volcanic eruption would be catastrophic for the birds.
During recent years, the Short-tailed Albatross has also been at a Japanese island other than Torishima.
The bird has been on the southerly island of Minami-kojima, one of the Senkaku Islands..
12 adult birds were found there in 1971. Breeding was not confirmed there until 1988.
A population of 75 birds was estimated there in 1991 (among them 15 breeding pairs). Since then, about 100 birds have been at the island.
During late 2012, the uninhabited Senkaku Islands were in the news due to tension between Japan and China. In Chinese, they are the Diaoyu Islands. Translated into English, they are the Pinnacle Islands.
They are located 200 nautical miles east of the mainland of China, 200 nautical miles southwest of the Japanese island of Okinawa, and about 120 nautical miles northeast of Taiwan.
The Senkaku Islands are uninhabited by people, but they are now inhabited by birds, the rare Short-tailed Albatrosses.
The story, told above, of the decimation of the albatrosses at Torishima is well known. The story at the Senkaku Islands was, historically, and unfortunately, a similar sad one, of decline and disappearance, and then, later, recovery.
But the number of birds now at the Senkakus is not as large as at Torishima.
At the Senkakus, the albatrosses were also slaughtered for feathers.
In 1884, it was said that "the Senkakus were so awash with albatrosses that there was almost no room to set foot ashore".
In 1985, after victory in the Sino-Japanese War, Japan officially claimed sovereignty over the Senkaku Islands.
That same year, the Japanese government allowed a man named Tatsushiro Koga to "develop" the island and for he and his men to collect feathers of the "Aho-dori", the Short-tailed Albatross.
In 1897, they killed 160,000 of the birds, dramatically slashing the population.
In 1900, on the Senkakus, only a small number of Short-tailed Albatrosses could be found, containing, in all, just 20 to 30 birds.
In the years that followed, with the birds gone, the business on the island changed for a while to guano mining, and then to tuna fishing in nearby waters.
By 1940, people had left the islands, and not a single albatross was to be found there. As late as 1963, searches there found none.
In the late 1960s, the possibility of oil and natural gas reserves under the seabed around the Senkaku Islands was announced, and shortly after that the issue of territorial rights for the area between Japan, China, and Taiwan began, and, still, as of now, has continued.
But during the second half of the 20th Century, the population of the Short-tailed Albatross has been recovering. And now it is again a breeding bird in the Senkaku Islands, particularly on the one island there known as Minami kojima.
Also notable on the Senkaku Islands, on Uotsuri-jima, an endemic mammal has been found, the Senkaku Mole, Mogera uchidai.
Regarding the history of the Short-tailed Albatross in Japan, it should be noted that:
In 1958, the Japanese government declared the bird to be "a special bird of protection".
In 1962, the bird became a "special national monument".
In 1993, with the ""Act for the Conservation of Endangered Species of Wild Fauna and Flora"", the Aho-dori, or Short-tailed Albatross was designated by Japan as one of the "national rare species of wild animals", and therefore always to be protected.
Regarding the history of the Senkaku Islands, it might also be noted that:
From 1945 to 1972, the United States administered the islands before returning them to Japanese control under the Okinawa Reversion Treaty between the US and Japan.
In the central Pacific, at Midway Atoll (in Hawaii), 1 or 2 Short-tailed Albatrosses were present during the last 2 decades of the 20th Century. An incubating bird was found there in 1993, but the egg was abandoned.
More recently, in this century, a pair of Short-tailed Albatrosses came to Midway in 2007.
In 2009, they built a nest but no egg was seen.
In November 2010, however, an egg was discovered under the presumed male of the pair. It hatched on January 14, 2011. According to the US Fish & Wildlife Service, the fledged youngster left the island on June 11, 2011, surviving the tsunami which followed the Japanese earthquake of March 2011. Assumedly, that young albatross would not return to Midway for 4 to 6 years.
That 2011 Midway fledgling represents the first time that the Short-tailed Albatross has been known to breed outside Japanese territory.
In Canadian Pacific waters, the Short-tailed Albatross is classified as a threatened species. In US waters, it has been classified as an endangered species.
Back in Japan, at the Torishima breeding colony, adult birds return in October. Eggs are laid October-November. Young are fledged from May onwards.
The following text is from "The Birds of Japan: Their Status & Distribution", by Oliver L. Austin Jr. & Nagahisa Kuroda, published in 1953, and written when the Short-tailed (or Steller's) Albatross was thought to be extinct:
Diomedea albatrus (Pallas)
Steller's (Short-tailed) Albatross
Japanese name: Ahodori (meaning "fool bird")
This magnificent albatross is probably extinct. Its disappearance was caused partly by the volcanic eruptions which destroyed its former nesting grounds on Torishima, but primarily by the activities of the plume hunters of the late 19th and the early 20th centuries. The most-recent definite record is the one for the few birds banded on Torishima in 1933 and killed there in 1934 (cf. Austin 1949b: 283-295).
It formerly bred on Torishima in the southern Izu Islands, on the northernmost of the Bonin Islands, and on isolated islets in the southern Ryukyus and the Pescadores. Its nesting season was from November through April. After the young were on the wing, the birds moved northward along the Japanese coast to summer in the Bering Sea, and then down the west coast of North America as far as Baja California, before returning to their breeding grounds in late autumn. The spring flight past Japan was marked by the numbers of dark-colored immature birds it contained, which could be confused with the Black-footed Albatross. The immature Steller's differed from the adult Black-footed only by its larger size and its lighter-colored bill, neither of which could be discerned at a far distance. An adult Steller's could also be difficult, at a distance, to tell in the field from the adult Laysan Albatross.

At some of the above places, during FONT tours, seen both offshore and from shore.
The Marbled Murrelet, a small
seabird, has the curious and unusual trait of nesting high in the limbs of
old-growth coniferous trees in the forest.
Its nesting habits are so unusual for a seabird that they remained a mystery until 1974, when a nest was discovered in the Big Basin State Park, in Santa Cruz County.
Other than a smaller population in the Santa Cruz Mountains, the entire breeding range of the Marbled Murrelet in California is in the conifer forests on the immediate coast of Del Norte, Humboldt, and northern Medocino Counties.
Federally, the Marbled Murrelet is classified as THREATENED. In California, it is classified as ENDANGERED.
In Canada, the Marbled Murrelet is classified as a threatened species.
There is a fine book entitled "Rare Bird - Pursuing the Mystery of the Marbled Murrelet", by Maria Mudd Ruth, published in 2005, that is an excellent read about the bird.
47 SCRIPPS'S MURRELET ______ California, Washington State, both offshore
Now here's a name to try to say quickly:
It's now the name of what was part of the Xantu's Murrelet. Now Mr. Xantu only has a hummingbird for a namesake.
The AOU (American Ornithologists Union) split the species known as the Xantu's Murrelet in July 2012.
The Scripps's Murrelet, Synthliboramphus scrippsi occurs at sea mostly in California. Away from its breeding sites, it occurs north, rarely, to northern California and more rarely to Oregon and Washington State, and south to southern Baja California, Mexico.
It breeds on islands off southern California: San Miguel, Santa Cruz, Anacapa, Santa Barbara, San Clemente, and formerly Santa Catalina, and in western Baja California, Mexico on San Benito, and Coronado and San Jeronimo islands. On larger islands (such as San Miguel, Santa Cruz, and San Clemente), it is confined largely or entirely to offshore rocks.
In Mexico, the Scripp's Murrelet is classified as an endangered species.
48 GUADALUPE MURRELET ______
The other half of what was the Xantu's Murrelet is now the Guadalupe Murrelet.
breeds on offshore
rocks and islands off western Baja California, Mexico from Guadalupe Island
south to the San Benito Islands. Breeding is unconfirmed on San Martin Island,
in Baja California, and San Clemente and Santa Barbara Islands in California,
It presumably winters offshore within the breeding range along the Pacific coast of Baja California.
In Mexico, the Guadalupe Murrelet is classified as an endangered species.

53 YELLOW-NAPED AMAZON ______ Costa Rica
54 BEARDED SCREECH OWL ______ Guatemala
55 GLOW-THROATED HUMMINGBIRD ______ Panama
In Panama, the Glow-throated Hummingbird is classified as a critically endangered species.
56 RED-COCKADED WOODPECKER ______ North Carolina
57 TURQUOISE COTINGA ______ Costa Rica, Panama
The Turquoise Cotinga is one of the seven species of "blue cotingas".
In Central America, the Lovely Cotinga, Cotinga amabilis, the Turquoise (or Ridgway's) Cotinga, Cotinga ridgwayi, and the Blue (or Natterer's) Cotinga, Cotinga nattererii.
In South America, the Purple-breasted Cotinga, Cotinga cotinga (the first of 3 species in the genus described by Linnaeus), Banded Cotinga, Cotinga maculata, Plum-throated Cotinga, Cotinga maynana, and the Spangled Cotinga, Cotinga cayana.
Of these, the Turquoise Cotinga has one of the most restricted ranges, occurring only in southwestern Costa Rica and Panama.
In Panama, the Turquoise Cotinga is classified as a critically endangered species.
In 1941, when the then-young naturalist Alexander Skutch settled at his then-new farm "Los Cosingos" in southern Costa Rica, among the birds the he especially noted was the Turquoise Cotinga.
He referred it as being among the "colorful species" (and that it is) that resided there, including also the Fiery-billed Aracari, Golden-naped Woodpecker and Orange-collared Manakin, each of these birds also with a limited range.
Dr. Skutch lived at "Los Cosingos" for 62 years. The morning of the day when Alexander Skutch died there, Dana Gardner, a friend and the illustrator of many of Skutch's books, told of "a beautiful Turquoise Cotinga that came out to sun itself in a bare tree at the edge of Skutch's yard at Los Cosingos".
In 1969, Alexander Skutch wrote about the nest of the Turquoise Cotinga. He wrote that it was a long-sought nest for him to find.
The slight, open structure was situated on a trifurcation of the horozontal lowest branch of a Muneco tree, about 30 feet above a little-used path.
By standing on the top of his longest ladder and raising a mirror attached to a long pole, Skutch saw two buffy eggs spotted all over with brown.
As she had built the nest alone, so the grayish, speckled female incubated alone, often sitting continuously for two or more hours, and then remaining away for from half an hour to well over an hour.
The only sound Skutch ever heard from that female bird was a low whistling of her wings in flight.
That silence did not surprise Skutch, for he had never heard any other sound from the male, clad in its glossy plumage of a lovely shade of blue, with patches of deep purple on the throat and breast. Skutch never saw a male Turquoise Cotinga ever go near the nest.
During the FONT tour in southern Costa Rica in 2011, not far from Skutch's place, both the grayish, speckled female and the male Turquoise Cotinga with its lovely shade of blue, were seen well on exposed branches.
THE FOLLOWING I FROM THE TEXT OF A FEATURE HERE IN THE FONT WEBSITE ABOUT ALEXANDER SKUTCH
AND SOME OF OUR VISITS DURING FONT TOURS OVER THE YEARS,
written by Armas Hill
It was in January 2005 when we did our first FONT tour in Costa Rica after Alexander Skutch had died the previous year, at nearly 100 years of age.
That time, however, we did not visit the Skutch property. When we passed through the nearby southern Costa Rican city of San Isidro de General, it just did not seem the same, for me, to be in that area, knowing that Mr. Skutch was gone.
A few years later, during our FONT Costa Rica Tour in March 2010, we visited, for the first time in about 10 years, "Los Cosingos", the home of that famed naturalist Alexander Skutch.
During our tours in the 1980s & 1990s, we had visited the place often. And since March 2010, we visited again during our FONT Costa Rica tours in 2011 & 2012.
Many memories came back to me during that first visit for us after Skutch's passing, in March 2010.
Especially when I looked at the rooms in his house, and saw so many things just as he had them there, as he lived simplistically during the decades of the second half of the 20th Century. His clothing was on hangers in his closet. His books, so many of them, were on the shelves. His old typewriter was there on his desk, as was an equally old sewing machine nearby. Perhaps all of the letters that he had received over the years were neatly in piles held together by rubber bands.
On the outside porch, there were the same chairs where Alexander Skutch and I had sat during my visits in previous years. From those chairs, more than once, we saw together a Turquoise Cotinga perched high in a treetop.
In March 2010, during our morning at "Los Cosingos", when our group looked into that same tall bare tree as I had so many times in the past, there was, incredibly, as blue as could be, once again, a Turquoise Cotinga!

In Mexico, the Sinaloa Martin has been classified as a species of special concern.
66 BICKNELL'S THRUSH ______ (breeds in the northeast US & eastern Canada)
The Bicknell's Thrush has been found during FONT tours in the Dominican Republic, where most occur during their non-breeding season.
The wintering range of the Bicknell's Thrush is restricted to the Greater Antilles of the West Indies, on the islands of Hispaniola, Cuba, Jamaica, and Puerto Rico.
However, most, by far, winter in the Dominican Republic on Hispaniola.
The Bicknell's Thrush, in its wintering territory, is typically shy and wary. It searches for invertebrates and fruits on the ground or in the sub-canopy of moist broadleaf forest, or broadleaf forest with few pines mixed in. The bird prefers dense understory.
Surveys conducted in the 1990s in the Dominican Republic found the following regarding the Bicknell's Thrush occurring as a seasonal non-breeding resident:
75 per cent in wet and mesic broadleaf forests
19 per cent in mixed pine/broadleaf forests
6 per cent in pine-dominated forests.
Birds were found at all elevations from sea level to 6,600 feet above sea level. Most, that is 62 per cent, were in primary montane forests higher that 3,000 feet in elevation.
In its migration, the Bicknell's Thrush can be found at some lowland localities in the Dominican Republic.
During surveys in the Dominican Republic in the 1990s & the early 2000s, places in high elevations where the Bicknell's Thrush was found included:
Sierras de Bahoruco, Neiba, and Martin Garcia, and the Cordilleras Central, Septentrional, and Oriental. It is most common in the Sierra de Bahoruco and the Cordillera Central.
Other places included the Los Haitises National Park and less so in the Del Este National Park.
The surveys seem to have found some sexual segregation among birds wintering in the Dominican Republic with males mostly in undisturbed montane forests, while females and birds of the year in younger, or more disturbed forests.
The arrival of Bicknell's Thrushes in the Dominican Republic is thought to be in late October and early November.
The birds probably start their northward spring migration in early to mid-April.
In Canada, where Bicknell's Thrushes nest, the bird has been classified as a species of special concern.
67 BENDIRE'S THRASHER ______ Arizona
68 SPRAGUE'S PIPIT ______ Texas (the species breeds in & near Montana)
In Canada, the Sprague's Pipit is classified as a threatened species.
69 CERULEAN WARBLER ______ Costa Rica, Delaware, Guatemala
Setophaga (formerly Dendroica) cerulea
THE FOLLOWING IS FROM THE "BIRDLINE" by Armas Hill on November 8, 2011:
There's a rather new book about the Cerulean Warbler entitled "Cerulean Blues: A Personal Search for a Vanishing Songbird", written by Katie Falon.
"Cerulean Blues" describes the plight of the Cerulean Warbler as it struggles to survive in ever-shrinking suitable habitat.
It is now said to be the fastest declining warbler species in the United States, with 3 per cent of its total population lost each year since 1966.
That means that there are now 80 per cent fewer Cerulean Warblers that there were 40 years ago, and their numbers continue to drop, due to factors such including deforestation.
In Canada, the Cerulean Warbler has been classified as a species of special concern.
70 PINK-HEADED WARBLER ______ Guatemala
Cardellina (formerly Ergaticus) versicolor
71 RUSTY BLACKBIRD ______ Alaska, Nebraska
The Rusty Blackbird has had one of the steepest population declines of any North American bird in recent years.
Breeding bird survey analysis shows a significant decrease of approximately 99 per cent, that is 12.5 per cent per year, from 1966 to 2005 throughout the bird's range.
A Quebec database, and several other data sources, corroborate a decline of the Rusty Blackbird population by approximately 90 per cent during 30 years from about 1974 to 2004.

83 LAYSAN ALBATROSS ______ Washington
In Mexican waters, the Laysan Albatross is classified as a threatened species.
The Laysan Albatross has been seen at sea during FONT Japan Tours, during nearly every pelagic ferry trip on the Pacific Ocean off the coast of the main Japanese island of Honshu. There have been over 25 such pelagic trips since 1994.
84 MURPHY'S PETREL ______ (a rarity in western North America, offshore)
85 MOTTLED PETREL ______ (a rarity in western North America, offshore)
86 FEA'S PETREL ______ North Carolina, offshore

94 MONTANE SOLITARY EAGLE ______ Costa Rica, Guatemala
Buteogallus (formerly Harpyhaliaetus) solitarius
In Mexico and Panama, the Montane Solitary Eagle is classified as an endangered species.
95 CRESTED EAGLE ______ Guatemala
In Mexico and Panama, the Crested Eagle is classified as an endangered species.
96 HARPY EAGLE ______
The Harpy Eagle is sparsely distributed throughout its extensive range in Central & South America.
It has been extirpated in a large part of its former range, particularly in the north in central & northern Central America, and in the south in northern Argentina and southern Brazil.
The species occurs in interrupted expanses of lowland tropical forest. The low overall population and a slow reproductive rate make shooting a significant threat.
Between October 2000 & December 2006, nests
of Harpy Eagles were
found in Panama
of 25 breeding pairs in the province of Darien.
Most were in tropical rain forest at an average altitude of nearly 400 feet above sea level, ranging in elevations from 150 to about 900 feet. Nest densities are estimated to be 4 to 6 in about 50 square miles.
Each breeding pair occupies from 8 to 12 square miles of forest. This nesting density of Harpy Eagles is the highest that's known
for the species throughout its entire breeding range.
The Harpy Eagle is the national bird of Panama. In Panama and Mexico, the Harpy Eagle is classified as an endangered species.

98 BLACK RAIL
______ Delaware, Costa Rica, North Carolina, Texas
In Mexico and Panama, the Black Rail is classified as an endangered species.
99 CORN CRAKE ______
The Corncrake is a European species that has greatly declined during recent decades.
When it was more common in Europe than it is today, it occurred as a rarity along the East Coast of North America in the fall.
Most recently, there have been occurrences on Briar Island, off Nova Scotia, Canada on May 4 & 5, 1993 (the most recent) and on the island of Saint-Pierre (in North America, off Canada, but part of France), on October 22, 1989.
Earlier Canadian occurrences were in Newfoundland in September 1928, and prior to that, further north on Baffin Island.
In the US, one was on Long Island, New York, November 2, 1963.
Historical records in the United States (mostly prior to the 20th Century) were in Maine, Rhode Island, Connecticut, New Jersey (in Salem in 1854 and in Dennisville in 1905), and Maryland (in what is now Stockton in Worcester County in 1900).
4 of the 5 Corncrake specimens from Long Island, New York were collected prior to the 20th Century.
The Corncrake was described by Linnaeus in 1758.
Outside North America, the Corncrake has been found during FONT tours in Bulgaria, Hungary, Poland, Romania.

100 PIPING PLOVER ______ Colorado (where rare), Mexico, North Carolina, Texas
In Canada and Mexico, the Piping Plover is classified as an endangered species.
The Piping Plover has been seen during FONT tours in Mexico on the Yucatan Peninsula.
101 MOUNTAIN PLOVER ______ Colorado, Kansas (where rare)
The population of the Mountain Plover has seriously declined in the last 25 years.
The species has been classified by Birdlife International as a "vulnerable" species, but more recently its status has been downlisted to "near threatened".
It has been said that about 80 per cent of the Mountain Plover population winters in California, with nearly a quarter of them in the Central Valley.
During a census in 1998, 2.663 birds were counted , with the two largest flocks containing about 250 birds each. One of those flocks was in Yolo County, and the other was in the Imperial Valley.
During every FONT tour in Colorado, and one in nearby Kansas, the Mountain Plover has been seen.
THE FOLLOWING IS PART OF A NARRATIVE RELATING TO THE FONT COLORADO TOUR IN APRIL 2010,
REFERRING TO THE "CAST OF PLOVERS IN EASTERN COLORADO", AMONG THEM THE MOUNTAIN PLOVER,
AND REFERRING TO A TOWN THERE WITH AN ANNUAL "MOUNTAIN PLOVER FESTIVAL",
written by Armas Hill, leader of the tour
We were heading east into the the plains
of eastern Colorado for the avian "curtain call" of our tour, with
the cast of plovers that occur there.
In addition to the not so aptly named Mountain Plover, that we've seen in the past, we've also seen Snowy, Piping, and Semipalmated Plovers, as well as Killdeer.
This time, the Snowy Plover was a "requested bird" during the tour, but I had thoughts of its name, "Snowy". being more appropriate than usual during this tour, with snow falling and accumulating around us as we traveled along the interstate highway.
But that was not to be the case. When we saw the Snowy Plover, later that day, by a pond in the plains, there was no snow, and the sun had broken through the clouds.
There, at that spot with the Snowy Plover, there were not flurries of snow, but there was a flurry of other birds, notably shorebirds. There were Avocets, in strong breeding plumage, Black-necked Stilts, Western Sandpipers, a Dunlin or two (a first for our tours in Colorado), Long-billed Dowitchers, and a fine flock of Wilson's Phalaropes, with bright, boldly-patterned females and pale males, doing what phalaropes often do when they feed, that is spin about on the water.
These birds were not far from a small place called Karval. Many people may not have heard of that little place in eastern Colorado, but it's rather renowned in those parts as being the place where, at that time, for 4 consecutive years, a "Mountain Plover Festival", was held during the last weekend in April.
We learned of it in another nearby small Colorado town, where a waitress in a small restaurant along a main street, pulled up for us information on the computer about the festival. It wasn't far sway, so we decided to go.
When we visited Karval, the last place where we went during the tour, we found that it was really not much a town.
It too had a main street of sorts, but with no restaurant, shops, or other such establishments.
Rather it was more like a center, with in fact a Community Center, for various large expansive ranches in the area.
On those private lands, during one weekend of the year, visitors can overnight at such a ranch, eat meals there, and with others see their special bird, the Mountain Plover along with other birds of the prairie.
Karval was certainly a unique place. I know of no other that has a "Mountain Plover Festival".
I mentioned the "cast of plovers" in eastern Colorado, noting the Mountain, Snowy, Piping, Semipalmated, and Killdeer. Additionally, Black-bellied and American Golden Plovers can appear in the region in migration.
Thus, making it a region where nearly all of the regularly-occurring plovers of North America have been found.
(The Pacific Golden Plover is the exception.)
In Canada, the Mountain
Plover is classified as an endangered species. In Mexico, it is
classified as a threatened species.
102 LONG-BILLED CURLEW ______ Arizona, California, Colorado, Kansas, Nebraska, North Carolina, Mexico
In addition to the places above, the Long-billed Curlew has been seen during FONT tours in Panama, Texas and Washington State. The species is rare in North Carolina and Panama.
In Canada, the Long-billed Curlew is classified as a species of special concern.

103 BLACK-TAILED GODWIT ______
note about HUDSONIAN GODWIT ______
105 SEMIPALMATED SANDPIPER ______ Alaska, Arizona (where rare), California, Colorado, Delaware
In addition to the places above, the Semipalmated Sandpiper has been seen during FONT tours in Florida, North Carolina, Texas
and outside the US during FONT tours in: Barbados, Belize, the Cayman Islands, Costa Rica, the Dominican Republic, Ecuador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Panama, Puerto Rico, and Venezuela.
In 2012, the Semipalmated Sandpiper was uplisted by Birdlife International to the category of being a "Near-threatened species" as it has had a moderately rapid population decline during the past 3 generations (22 years).
Causes seem to include:
an over-exploitation in the non-breeding range (notably in Suriname), and a reduced food supply at key staging areas (in the eastern US).
The SEMIPALMATED SANDPIPER is referred to (with text & photos) in a narrative later in this list, relating to the American subspecies of the RED KNOT, Calidris canutus rufa (number #137 in this list).
106 BUFF-BREASTED SANDPIPER ______ North Carolina
Outside North America, the Buff-breasted Sandpiper has been seen during FONT tours in far-southern Brazil.

112 MEXICAN SHEARTAIL ______ Mexico (endemic)
There are two 2
geographically distinct populations of the Mexican Sheartail: one in the northern Yucatan where it is
threatened, and another smaller population in Veracruz where it is critically
The northern Yucatan population of the Mexican Sheartail is found exclusively in a narrow coastal strip, only about one kilometer wide, mainly between mangroves and tropical deciduous forest. It has also been found to breed in gardens.
The Veracruz population occurs in undisturbed, dry deciduous forest and overgrazed habitats at about 25 kilometers inland.
The Mexican Sheartail has been observed feeding at flowers of Ipomoea, Justicia, and Helicteres guazumaefolia, and its diet is supplemented by small anthropods. The bird is often close to the ground.
In the northern Yucatan, nesting takes place August-April, with recently fledged young reported in February and March.
In Mexico, the Mexican Sheartail is classified as an endangered species.

According to the US Fish & Wildlife Service, during surveys of nesting areas of Kirtland's Warblers in the US in 2011, there were 1,838 singing males, up from the record lows of 167 in 1974 & 1987.
Recently, numbers of Kirtland's Warblers have increased, not only in Michigan (the only place where, for years, the species was known to nest), but also in Wisconsin, USA and Ontario, Canada, at the only known breeding sites for the species outside of Michigan, USA.
Since 2007 (and as of 2011), at least 54 fledglings have been produced in Wisconsin, and at least 23 in Ontario.
June 2007 was an extraordinary month relating to the Kirtland's Warbler. 23 days and 700 miles (1,100 kilometers) apart, the first nests documented outside Michigan, in recent years, were found.
These recent historical occurrences were in Wisconsin and Ontario. Since then, nesting has increased in Wisconsin and has persisted at one site in Ontario.
The first 2007 nest in Wisconsin was in a pine plantation in Adams County in the central part of the state. That nest contained 5 eggs.
Before that breeding season ended, two more nests were found in Wisconsin. No young warblers were seen, but adults fed single Brown-headed Cowbirds at two of the nests.
Later, at least 45 Kirtland's Warbler nests produced an estimated 54 to 72 fledglings in Adams County, Wisconsin from 2007 to 2011.
A noteworthy characteristic at the main study site in Adams County is that only 12 per cent of the trees are Jack Pines.
Since 2006, reports of Kirtland's Warblers during the breeding season in Wisconsin have been in Jackson County, in the south-central part of the state, and in Bayfield, Douglas, Marinette, Vilas, and Washburn Counties in the north.
A Marinette County nest fledged 3 young in 2009 - at that time the only Wisconsin nest known outside of Adams County.
The recent Ontario Kirtland's Warbler nesting site has been at an active military training facility, at the Canadian Forces Base Petawawa, about 100 miles (160 kilometers) north of Ottawa.
At that site in June 2007, a Kirtland's Warbler nest with two hatchlings and two unhatched-eggs was found under the low branches of a Jack Pine.
That was actually Ontario's second breeding record for the Kirtland's Warbler. A pair and one fledgling were observed at Midhurst, Ontario in 1945.
In Ontario, from 2007 to 2011, a total of 7 Kirtland Warbler nests produced at least 23 fledglings. In 2011, 1 pair and 1 fledgling were confirmed, but there has been some uncertainty, overall, due to restrictions in the coverage area.
In Canada, the Kirtland's Warbler is classified as an endangered species.
During the winter, the Kirtland's Warbler occurs only in the Bahamas, in the West Indies.
129 BACHMAN'S SPARROW ______ North Carolina
130 HENSLOW'S SPARROW ______ North Carolina
In Canada, the Henslow's Sparrow has been classified as an endangered species.
131 CHESTNUT-COLLARED LONGSPUR ______ Colorado

132 McKAY'S BUNTING ______ Alaska
Calcarius (formerly Plectrophenax) hyperboreus
The McKay's Bunting is known to breed only
on the Alaskan islands of Hall and St. Matthew in the Bering Sea. A few
are sometimes present in the late spring on St. Lawrence Island, and in the
summer it is rarely on the Pribilof Islands.
In the winter, it is rare to uncommon along the west coast of Alaska, and rare in the winter in interior Alaska, on the Aleutians, and south along the West Coast of North America south to Oregon,
Some think that the McKay's Bunting is a subspecies of the Snow Bunting.
133 BLUE-AND-GOLD TANAGER ______ Costa Rica, Panama
In Panama, the Blue-and-gold Tanager is classified as a vulnerable species.

Some Subspecies of North
& Middle America classified as ENDANGERED:
135 "COZUMEL CURASSOW" ______ Mexico (endemic to Cozumel Island)
Crax rubra griscomi
In Mexico, the "Cozumel Curassow" is classified as an endangered subspecies.
136 "MASKED BOBWHITE" ______ Arizona, Mexico
Colinus virginianus ridgwayi
Historically, this distinctive subspecies of the Northern Bobwhite
known as the "Masked Bobwhite" was found in southern Arizona in
the US & in Sonora, Mexico.
It disappeared from the US portion of its range in the early 1900s. A reintroduction into Arizona was done in the 1970s, and now it is rare both there and in Mexico.
In Mexico, the "Masked Bobwhite" is classified as an endangered subspecies.

137 RED KNOT ______ Alaska, California, Delaware, North Carolina, Texas, Washington State
Calidris canutus rufa
In addition to the places noted above, the American subspecies of the Red Knot has been seen during FONT tours in:
Argentina, Brazil, Chile, the Galapagos, Mexico, Panama, and Puerto Rico.
The inclusion of the Red Knot here is in relation to one
Calidris canutus rufa, the subspecies that breeds in far-northern Canada and migrates to southern South America, as far south as Tierra del Fuego.

The following text is from a special feature, as it was given on the "Birdline" by Armas Hill
on the internet on June 13, 2005,
relating to RED KNOTS and other shorebirds that have staged annually over the years,
in the late-spring, along the shores of the Delaware Bay in the USA.
Those KNOTS having flown there from Patagonia in South America.
Some of this feature was on the Birdline on the Radio on June 15 & 22, 2005.
Other text of this Birdline feature, given on the internet only, on June 22, is also given here.
The feature relates to the connection in the birdlife throughout the Americas, in places that
geographically are so far apart, with the KNOTS staging in eastern North America before
nesting in Arctic Canada and then migrating to far-southern South America, year after year.

RED KNOTS IN AMERICA IN PERIL
in Chile, Argentina, Delaware & New Jersey, and northern Canada
written by Armas Hill
Thousands of miles away from us here in North America, in far-southern South America, there's a ferry that carries mostly trucks and a few cars across the Strait of Magellan.
Even though it's at the eastern end of the strait, not far from the Atlantic, it's in Chile.
In the water, by the boat, there are Commerson's Dolphins, with their beautiful black and white pattern.
Also in the water, Magellanic Penguins fish.
In the sky, King Cormorants fly, with black-and-white coloration, like the dolphins and the penguins.
In the air, above the feeding penguins, there are South American Terns emitting their raucous calls as they fly about.
Southern Giant Petrels fly by, ready to scavenge.
At a distance, over the sea, Black-browed Albatrosses continuously glide up and down in arcs.
Also at a distance, but on a beach, there's a flock of shorebirds that only recently arrived from somewhere else.
It's November. When it's spring, going into summer, at the Strait of Magellan, back in the Northern Hemisphere, from where the shorebirds came, it's fall, going into winter.
All of the other wildlife just mentioned resides year-round in the Southern Hemisphere.
But the shorebirds have gone from one summer to another to feed on the beach there, in the intertidal zone of mollusks and crustaceans.
The shorebirds in a flock are Red Knots, the subspecies Calidris canutus rufa, that inhabits the Americas.
In that area of Chile, just referred to, nearly no people live. There are no towns or cities. Even the ferry operators live in small settlements some distance away. There's no pollution, and virtually no noise, other than what is natural..
If one were to walk along the coast with the knots, just a short distance from the sound of the ferry, only surf and natural sounds such as the raucous calls of the terns would be heard.
Also in southern Argentina, but a thousand miles to the north, along the Atlantic coast, there are long and clean beaches that extend for miles. Again, many of those miles are without people, pollution, and unnatural noise.
Along some stretches of that coast, in Patagonia, there are seals and sea lions, Killer Whales and dolphins, in and beyond the surf, and Southern Right Whales in some of the bays.
Various gulls and terns are throughout.
Also along parts of that Argentine coast, there can be thousands of Manx Shearwaters (in November, having come from the European side of the North Atlantic), and groups of big, colorful Burrowing Parrots that reside in the sandy coastal bluffs by the ocean.
Along the sandy beaches below the bluffs and beyond for many miles, there are, again, flocks of shorebirds. Again, during the Austral spring and summer, they are Red Knots. Birds in these flocks until recently numbered in the thousands.
Inland, just a few kilometers, from one of those coastal locations in Argentina, there's a large farm property with many acres of natural shrubby vegetation.
There's a lot of (natural) sound there, as the terrain is filled with mockingbirds of two species that are very vocal.
There are a number of interesting landbirds, including one endemic to Argentina, the Carbonated Finch, a sparkling bird! (Yes, that's a pun.)
What has also been there is another songster, the Yellow Cardinal. (Instead of being red & black as is the Cardinal in North America, it's yellow and black.)
The Yellow Cardinal in South America
The farm just described is owned by a man named Senor
(or Mr.) Manana.
Yes, it's true, "Senor Manana".
As the Yellow Cardinal that's been on his property is prized as a cage bird, due to its beautiful song and striking appearance, people sometimes come there to capture it.
With too much of that unfortunate activity recently, that species has now been classified by Birdlife International as "endangered", the second level after "critically threatened".
With too much of that activity, that species won't have too many more "mananas" (or "tomorrows", in Spanish).
Down the highway a bit from Sr. Manana's farm, there's a hotel, where young ornithologists have periodically stayed, the last few years, from October onwards, as they have been banding the Red Knots on the nearby beaches.
During our tours, we have stayed at that same hotel.
In conversations there at the hotel, even just a decade ago, it was not anticipated that those shorebirds there would be declining as drastically as the pretty songster, the Yellow Cardinal, down the road.
About a week before I wrote this essay (back on Sunday, June 5, in 2005), in Delaware USA, people with the Division of Fish & Wildlife of that state, were continuing their efforts to monitor the shorebirds along the Delaware Bayshore, as they had been doing every year since 1997.
Along the coast that day, near South Bowers Beach, there was a lingering group of shorebirds that contained about 600 Knots, 600 Sanderlings, 1,500 Ruddy Turnstones, and 1,500 Semipalmated Sandpipers.
During 6 hours with the birds that day, the researchers found about 50 marked, or banded, birds.
About half of them were Red Knots, marked during the previous three years (2002-2004), with some lime flags.
At least 1 was flagged in Chile (maybe by the beach by the Strait of Magellan), and 3 of the Knots were flagged in Argentina (probably on the Atlantic beach in northern Patagonia, near Senor Manana's farm).
Every year, the Red Knots, Calidris canutus rufa, make a nearly 18,000-mile round-trip journey between Argentina & Chile and far-northern North America (Arctic Canada), where they nest.
The first stage of their northbound migration includes, as it has for a long, long time, a 3 to 4 thousand mile flight (usually non-stop) to the Delaware Bay shores.
Upon their arrival, the hungry birds must feed on the Horseshoe Crab eggs, laid on the beach at that time of year, in the late-spring.
That feeding is necessary for the birds to continue, with the needed energy, on the rest of their migration, with yet another long flight to northern Canada.
The Red Knot depends almost exclusively on the Horseshoe Crab eggs to successfully complete the migration to their nesting grounds.

The Red Knot population, visiting the Delaware
Bay shores in the spring, has numbered more than 150,000 birds.
Recent surveys, however, have shown that number has dropped dramatically to an estimated 15,000 birds.
In the last 10 years, according to those studies, this Red Knot population has declined more than 90%.
Surveys in the Delaware Bay area have fluctuated from about 16,000 Red Knots in 2003 down to about 13,000 in 2004, then up to about 15,000 in 2005.
Added to this is a sad statistic relating to a recent survey in South America. In 2005, there, only 17,600 knots were counted, a decline of 40% from the previous year.
The Red Knot, in the Americas, may now be said to be the most endangered shorebird population in the world.
Not just the Red Knot, but 5 other species of shorebirds, are dependent upon the horseshoe crab eggs along the Delaware Bayshore.
In 2005, according to New Jersey's chief endangered species biologist, surveys of Horseshoe Crab eggs in New Jersey and Delaware indicated, where as normally 4,000 eggs are laid per meter, the count was about 1,500. That was not good.
Also, in both New Jersey and Delaware, Horseshoe Crab eggs have been harvested, with annual harvests being about 150,000.
Thus, in certain years, there have been 300,000 less Horseshoe Crabs, depleting further the food supply needed by the Red Knot and 5 other species of shorebirds.
A grouping of 11 organizations have joined together to petition the state governments of New Jersey and Delaware, with a proposal of 4 specific actions urgently needed to save the situation, due to all of the evidence that there is of a "death spiral" for the Red Knot.
The 11 organizations are these:
the American Bird Conservancy, the American Littoral Society, Citizens Campaign for the Environment, Defenders of Wildlife, the Delaware Audubon Society, the Delaware Riverkeeper, the National Audubon Society, the New Jersey Environmental Federation, the NJ Public Interest Research Group, and the Sierra Club.
The 4 actions:
1) institution of a moratorium on Horseshoe Crab harvesting
2) support efforts in surrounding states to enact such a moratorium and measures to conserve the shared resource
3) support efforts to federally list the Red Knot, Calidris canutus rufa, under the Endangered Species Act
4) continue bay-wide efforts to reduce human harassment (of all kinds) of foraging shorebirds.
Truly time is of the essence for helping the Red Knot, to be as it has been in the Americas. Without such help, again, there simply may not be that many more "mananas" for the bird, on the beaches not that from from Senor Manana's farm.
Now, some more information regarding the history of shorebirds including the Red Knot along the Delaware Bay, as given by Armas Hill in the Birdline Feature on the internet, on Birdline Delaware and the Philadelphia Birdline, on June 22, 2005, as a continuation of the June 13 feature that preceded it:
It was noted that in 2004, survey-work indicated that the late-spring staging population of the Red Knot along the Delaware Bayshore was about 13,000 birds.
And it was noted that was considerably less than what the population was a couple decades previously.
It was also noted last time that the Red Knot is just one of about a half-dozen species of shorebirds that stage in the late-spring along the shores of the Delaware Bay.
Over 90 per cent of the shorebirds that flock in the late-spring along the Delaware Bay are of 4 species: Semipalmated Sandpiper, Ruddy Turnstone, Red Knot, and Sanderling.
On May 29, 2006, this flock of Semipalmated Sandpipers
was along the Delaware Bay at Port Mahon, in Delaware.

Smaller numbers of
Short-billed Dowitchers and Dunlin also occur. That makes 6 species
of shorebirds in addition to Laughing Gulls that feed on the Horseshoe
Crab eggs on the beach. Also, about a dozen other species of shorebirds
occur in the area in the spring.

During the years 1982 to
1995, in the spring, as many as 272,000 Semipalmated Sandpipers were
counted on both shores (Delaware & New Jersey) of the Delaware
The high-day of the year, during that period, averaged 112,000.
After 1988, no day-count exceeded 100,000.
These Semipalmated Sandpipers non-stop 2,700 miles from Surinam, in northern South America, to the Delaware Bay shores. It is an astonishing journey, really, for those small birds - smaller yet, weighing less than an ounce when they arrive.
Once by the Bay, they fuel up on the Horseshoe Crab eggs, as they must, to continue their migration north. This feeding is also necessary, in the same way, for the same reason, for the other shorebird species about to mentioned.
During the years just referred to, the annual high-day for Ruddy Turnstones averaged 70,000.
It was as high as 108,000 in 1989.
The Ruddy Turnstones by the Delaware Bay in May probably represent about three-quarters of the eastern North American population. These birds winter from South Carolina south to southern South America, along the Atlantic Coast.
With their sturdy bills, Turnstones not only turn stones, they also dig holes in the sand to expose more Horseshoe Crab eggs. They thus provide what could be called a foraging service for other shorebirds.
Regarding Red Knots, most of which migrate to the Delaware Bay from as far south as Tierra del Fuego (in far-southern South America), nearly as many as 100,000 have been counted during one day (96,000). The average high-day for the species during the survey period (from 1982 to 1995) was 48,000.
Many of the Sanderlings that stage by the Delaware Bay in May come mostly from wintering-quarters in Brazil. But some also come from the sandy coasts of Peru and Chile on the Pacific side of South America. A few winter further north, in for example, Florida.
The maximum high-count for Sanderlings by the Delaware Bay in May started to decline in the early 1980's. From 56,000 in 1982, it dropped steadily to a level of 10,000 in 1993, 1994, & 1995.
That decline followed a substantial decrease of perhaps 80 per cent of the Sanderling population along the East Coast of the USA from 1972 to 1982, continuing the downward spiral.
Generally, over the years, in the Delaware Bay area, Sanderlings have been more to the south, closer to the mouth of the Bay.
To continue our look back at shorebirds by the Delaware Bay, and to continue our effort to get a good perspective of what has been, we'll go now to the writings, done back in 1937, by one of the foremost ornithologists of that region in those days, Witmer Stone. His work, published that year, was entitled "Bird Studies at Old Cape May".
What Witmer Stone did NOT refer to in that work were large flocks of shorebirds as just mentioned, being by the Delaware Bay on the New Jersey side, at places such as Reed's Beach, where since then such large flocks have been.
One could assume, wrongly perhaps, that those flocks of Knots and Turnstones and the like were there, but that Mr. Stone did not know about them. However, when reading through his book, it is apparent that ornithologists of that day did know what was about, and so another assumption can be made that such large flocks simply weren't there.
What Witmer Stone did refer to was the rampant shooting of shorebirds that formerly took place along that part of the coast of eastern North America.
The Red Knot, he said, was known to the gunners as the "Robin Snipe" or "Red-breasted Snipe".
It, along with the Dowitcher (in those days a single species), before the shooting was abolished, were among the most desirable of the shorebirds from the gunner's standpoint, as they both decoyed easily. Thus, they both, according to Stone, "nearly approached extermination".
The accounts in Stone's 1937 book refer to Knots occurring in southern New Jersey, in the early part of the 20th Century, in small groups of 150 or so, or in "low numbers" of less than a hundred. He relates that a gunner, for instance, in late-May 1907, shot 29 of them in Cape May County.
Something very important in relation to shorebirds happened in 1913. That year, the Federal Migratory Bird Law went into effect and the season was CLOSED on ALL shorebirds except the Woodcock, Black-bellied Plover, Golden Plover, and Snipe (known then as the Wilson's Snipe, as it is now known again today), and the two species of Yellowlegs.
In 1926, the two species of Plovers were put on the protected list, and in 1927 the Yellowlegs followed them.
The season on Woodcock and Snipe, the only two "shorebirds" remaining on the game list, was subsequently reduced to one month with a bag limit.
Populations of the shorebirds of coastal New Jersey were monitored in the late 1920's and early 1930's.
During that period, let's pick a year - 1931.
For that year, here's a ranking of SHOREBIRD SPECIES in New Jersey, during their northward spring migration in May, listing the most common first, and then those less so in descending order:
1 - Semipalmated Sandpiper
2 - Ruddy Turnstone
3 - Black-bellied Plover
4 - Semipalmated Plover
5 - Greater Yellowlegs
6 - Sanderling
7 - Least Sandpiper
8 - Dowitcher (nearly all Short-billed of course, but in those days as noted, it was a single species)
9 - Whimbrel (was then called the Hudsonian Curlew)
10 - RED KNOT
11 - Dunlin (was called then the Red-backed Sandpiper)
12 - Lesser Yellowlegs
13 - Western Sandpiper

The following shorebirds, overall during the period 1929-1934, were classified in New Jersey as "abundant" or "very common":
Semipalmated Sandpiper, Sedmipalmated Plover, Sanderling, Dowitcher, Least Sandpiper, Greater Yellowlwgs.
Notice, now, that the Red Knot was in the second category, those classified as "common".
In that grouping, there were these species:
Black-bellied Plover, Killdeer, Ruddy Turnstone, Dunlin, Red Knot, Western Sandpiper, Lesser Yellowlegs (less common during the northbound migration than during the southbound), Whimbrel, Pectoral Sandpiper, Spotted Sandpiper.
The author Peter Matthiessen wrote a fine book about shorebirds, published in 1967, and entitled "The Wind Birds".
In it, he also alluded to the widespread shooting of shorebirds that was referred to by Witmer Stone. That shooting was very prevalent in the late 1800's. It also continued in the early 1900's, even as some species started to show significant declines.
Matthiessen wrote that "under the circumstances, it's a wonder that any shorebirds survived into the 20th Century". They were shot in numbers, and they were trapped.
There was even a practice of "fire-lightning", that was commonly done, for example on Long Island NY, when after dark resting flocks of shorebirds, blinded by a bright beam, stood by while men stepped out from punts and wrung their necks.
Among the gunners of that era, Knots and Dowitchers, as noted earlier, were favorites. So were Golden Plovers and Eskimo Curlews, not only because of their fine taste and great numbers (yes, even so for the Curlew), but also because they were unsuspicious to a fault. The Eskimo Curlew would circle back over the guns, calling out to its fallen companions. That was a habit shared by the Dunlin, Dowitcher, and other species. The Dunlin was called "the simpleton" by Long Island hunters, reflecting the low esteem in which its brain was held.
After the legal protection for shorebirds came to be, as noted in 1913, for a number of species, through the 20th Century, things improved. For the Eskimo Curlew, it was too late.
Yes, shorebirds that at one time existed by the thousands, can in time disappear.
The ESKIMO CURLEW is referred to in a narrative later in this list (number #141).
The following is a passage from Alexander Wilson's "American Ornithology", written in the early 19th Century:
"Everyone who has been on the shore, on a day gleaming and cloudy, may have seen masses of these birds at a distance, appearing like a dark and swiftly moving cloud, suddenly vanishing, but then in a second, appearing at some distance, glowing with a silvery light almost too intense to gaze upon. These are the consequences of the simultaneous motions of the flock, at once changing their position, showing the dark gray of their backs, or the pure white of their underparts."
With these words, Alexander Wilson was writing about the Knot (in its winter plumage). In his day, the bird was called the "Ash-colored Sandpiper".
The scientific name, "Calidris canutus", refers to King Canute, who loved to eat it (the species does have a European population).
4 books, written over the years, have already been noted in this essay.
Another one is: "The Flight of the Red Knot" by Brian Harrington and Charles Flowers, published in 1996.
If you can get it, it's interesting, and with good background about the Knot.
FONT (Focus On Nature Tours) goes to southern South America, to Argentina & Chile. Although people don't normally travel to the opposite end of the world to see birds that migrate from their homelands, it is a nice experience to see the places where these birds go. And it's fascinating in a way to share the long migration of the KNOTS and other SHOREBIRDS.
Places to be visited in southern South America referred to in this bulletin include:
PATAGONIAN ARGENTINA: the coastal region with the miles of beaches, and Senor Manana's farm (with the YELLOW CARDINAL), north of the Valdez Peninsula, and TIERRA DEL FUEGO, in far-southern ARGENTINA.
During FONT Argentina tours, in addition to the Yellow Cardinal and Red Knot, other birds and wildlife in the preceding text have been seen, including:
Magellanic Penguin (including a colony with a million), Southern Giant Petrel, Black-browed Albatross, Manx Shearwater, South American Tern, Burrowing Parrot, Carbonated Finch, and Southern Right Whale, Killer Whale (or Orca), and seals and sea-lions..
And that's just some of the nature that we've observed!

138 "EASTERN LOGGERHEAD SHRIKE" ______ Ontario
Lanius ludovicianus migrans
Lanius ludovicianus migrans is critically endangered in Canada, with less than 35 pairs found in 2009. The vast majority of them breed in Ontario.
A recovery (captive-breeding and release) program is underway for the species in Ontario, with approximately 100 juvenile shrikes released annually there since 2006.
Overall, the Loggerhead Shrike has declined throughout North America, but especially so in the northeastern US, where Lanius ludovicianus migrans no longer occurs in much of its former range.
Lanius l. ludovicianus, the subspecies that occurs in the southeastern United States, has been seen during FONT tours in North Carolina and Florida.

Approximate years of some last sightings are noted in the texts below.
139 LABRADOR DUCK ______ (was in eastern Canada and the eastern United States)
Although the Labrador Duck lived in eastern Canada and the eastern United States, there is no real evidence that it actually lived or bred in Newfoundland or Labrador itself.
The Labrador Duck was always, in a way, a rather mysterious bird. It was distinctive-looking enough, being also called the "Pied Duck" or even the "Skunk Duck" in New York, where it was commonly shot along with other waterfowl.
But really nothing was known of the bird's behavior. Its unusual beak, with exceptionally numerous lamelline and a swollen cere, does suggest that it had specialized feeding habits. It was said to be a strong flyer and a good diver.
The only eggs of the Labrador Duck ever said to have been collected were put in a museum in Dresden, Germany, but there is some doubt as to their authenticity.
The Labrador Duck certainly inhabited in sandy bays and on islands from the Bay of Fundy south to New Jersey, where it was hunted in the autumn and winter. But, as said, there is no solid evidence that it occurred north of New Brunswick, Canada.
Probably the population of the Labrador Duck was smaller than thought. And even by the time it was scientifically described in 1788, its numbers were probably already substantially reduced, as the bird was simply overhunted.
It was common in food markets in New York City and Baltimore in the 1869s.
But only one Labrador Duck was seen after 1871, and that bird was shot on Long Island, New York in 1875.
140 ATITLAN GREBE ______ Guatemala (was endemic)
The Atitlan Grebe occurred at Lake Atitlan in Guatemala, being endemic to both the country and the lake.
The lake named Atitlan is about a mile above sea level. It has a shoreline of about 155 miles.
The grebe was first collected there in 1862, but it was not recognized as being different than the Pied-billed Grebe until 1929, when it was described by Ludlow Griscom (an ornithologist from the US) as Podilymbus gigas, noting that it was the "Giant Pied-billed Grebe" being nearly twice the size of the widespread Pied-billed Grebe. But its wings were small and weak. It was said to be nearly flightless.
In 1929, Griscom estimated the population of what he called Podyilymbus gigas to be about 100 pairs.
Alexander Wetmore, from the Smithsonian in the US, visited Lake Atitlan in 1936, and he estimated the number to be about the same.
But it was the American ecologist Anne LaBastille who studied the Atitlan Grebe the most, She first went to Lake Atitlan in 1960 to photograph the grebes and to make a census of their population. She continued to observe the species for 25 years.
During her first survey in 1960, she found the number of Atitlan Grebes to be about the same found by Griscom and Wetmore.
In 1964, doing further study, she found, in her census, 100 birds - that was about half of what had been found a few years earlier.
In November 1966, 86 birds were found.
Even with a considerable effort by LaBastille to save the Atitlan Grebe, probably the introduction of non-native Largemouth Bass into the lake in late 1950s, doomed the bird The non-flying adults, and especially their young, fell easy prey.
Anne LaBastille wrote a book about the Atitlan Grebe, entitled "Mama Poc''. The word "Poc" was the Mayan name for the bird.
So to capsulize, In the 1930s, there were an estimated 200 or so "Pocs", or Attilan Grebes. The population had decreased to 50-60 birds by the early 1980s. It is now believed to be extinct.
It has been said, and some still ay that this bird was a larger resident subspecies of the Pied-billed Grebe.
Before Focus On Nature Tours was formed in 1990, Armas Hill made a visit to Guatemala in 1981 during which he saw the Atitlan Grebe, one bird well and possibly another.
Lake Atitlan in Guatemala was the only place in the World
where the Atitlan Grebe lived.

breeder in northern Canada & a migrant in the central & eastern US)
The last sighting (unconfirmed) of the Eskimo Curlew in North America was in the 1980s.
The last sighting in South America was in 1939.
The last specimen of an Eskimo Curlew was a bird shot in Barbados, in the West Indies, in 1964.
By the 1970's, it was assumed that the species was gone, but there was a sighting (only) of a flock of 23 birds in Texas in 1981.
In the area of the Caribbean, the Eskimo Curlew was perhaps a rare migrant from late August to early November, except on the island of Barbados where it occurred regularly in American Golden Plover flocks during their southbound migration.
Formerly, the Eskimo Curlew was an abundant breeder in northwestern Canada, and it undertook a long migration south to central Argentina and back each year.
It was hunted by the thousands for food and sport on the western plains of the United States (during its northbound, spring migration), primarily from 1870 to 1900. By the beginning of the 20th Century, the bird had become relatively scarce.
Another, longer narrative about the Eskimo Curlew follows, beneath the illustration below.

Another name for the Eskimo Curlew was the "Doe-bird", sometimes spelled "Dough-bird". That name was due to the bird's acquiring of fatness for its long journey south.
As North America was being settled by the Europeans, the Eskimo Curlew was one of the most abundant birds on the continent.
It bred on the Barren Grounds of northern Canada. It wintered in far-southern South America. It migrated in between.
It was said, during its southbound migration, to have visited Newfoundland "in millions" darkening the sky.
John James Audubon, Elliot Coues, and other ornithologists of the early 1800s told of immense flights.
In the Prairie States, the numbers of Eskimo Curlews so resembled the tremendous flights of Passenger Pigeons that they were called "Prairie Pigeons".
A single flock alighting in Nebraska was said to have covered 40 to 50 acres of ground.
The Eskimo Curlew migrated south in August southeast to Labrador and Newfoundland, where they fed on "curlew berries" (Empetrum nigrum) and snails, gaining the weight needed for their long journey out over the sea to South America.
Easterly storms, such as hurricanes that time of year, sometimes brought them onto the coasts of New England and Long Island, New York. They often touched down on Lesser Antillean islands, such as Barbados, before continuing on to to the coast of Brazil, and then further to Argentina.
During their northbound spring route, after crossing the Gulf of Mexico, they arrived in March in southern Texas, and then continued up the western Mississippi Valley, and thence further north to where they would nest.
But from being abundant, the status of the Eskimo Curlew in the 19th Century certainly changed.
Incredibly, the Eskimo Curlew was not seen anywhere at its known breeding grounds for years after 1865.
Just over a century later, in 1987, a small nesting colony was said to be found in the Canadian Arctic, that was maybe the last.
The last breeding grounds of the Eskimo Curlew in northern Canada are said to have been in either Ungava or Franklin.
The last Eskimo Curlews were either seen or shot at these places as follows:
in Illinois in 1872
in Ontario in 1873
in Ohio in 1878
in Arkansas and Michigan in 1883
in South Dakota and Oklahoma in 1884
in Minnesota in 1885
in Louisiana, Pennsylvania, and Newfoundland in 1889
in Indiana in 1890
in Iowa in 1893
in Prince Edward Island in 1901
in Kansas, Missouri, and Nova Scotia in 1902
in Quebec in 1906 (fair-sized flocks in the fall were in Quebec until 1891)
in Wisconsin in 1912
in Maryland, and Bermuda in 1913 (fair-sized flocks were in Bermuda until 1874)
in Massachusetts in 1916 (fair-sized flocks were in Massachusetts until 1883)
in Nebraska in 1926 (there was a more-recent report in Nebraska in 1987)
in Maine in 1929 (fair-sized flocks were in Maine until 1879)
in Labrador and Long Island, New York in 1932 (fair-sized flocks in the fall were in Labrador until 1892)
in South Carolina in 1956
in New Jersey in 1959
in the Bahamas in 1963
in Barbados in the Lesser Antilles in 1964, when one was shot.
No spring migrant was seen anywhere other than Texas since 1926.
Along the Gulf coast of Texas, the last confirmed sighting, with a photograph, was at Galveston in 1962. A flock of 23 birds was reported there in 1981.
There were additional, but unconfirmed records of Eskimo Curlews:
in Texas and Canada in 1987 (the Canadian "breeding site" noted above), in Nova Scotia in 2006, and in Argentina in 1990.
The last Eskimo Curlews seen and confirmed at wintering grounds in South America, were in Argentina back in n 1939.
With prevailing westerlies or strong storms, Eskimo Curlews were at times seen across the Atlantic Ocean:
Sighted or shot:
in England in 1852 (2 birds) and 1887.
in Scotland in 1855, 1878, 1880.
in Ireland in 1870.
142 GREAT AUK ______ (was in the area of the North Atlantic Ocean)
THE FOLLOWING RELATES TO THE GREAT AUK AS IT ONCE WAS IN ICELAND,
written by Armas Hill, the leader of FONT tours there
The Great Auk also bred in northeastern North America and in the winter it swan south along the American coast as far as North Carolina, sometimes walking up on the beaches.
The Great Auk was a large flightless seabird that became extinct in 1844.
Although they were flightless, Great Auks, as good swimmers, were strongly migratory, with some, probably from Newfoundland, occurring in the winter as far south along the Atlantic coast of North America as the Carolinas.
It can not be questioned that Great Auks bred on small islands, skerries, and rocks off the coast of Iceland.
Bones of 8 individuals were found at Kyrkjuvogy and Baejsker.
According to tradition, there were 4 small Icelandic islands where Great Auks either formerly bred, or habitually roosted.
All were called "Geirfuglasker" (or Gare Fowl Skerries - "Gare Fowl" was the Icelandic name for the Great Auk).
For two of those islands, the record was only by word of mouth and quite vague.
The two well-documented Icelandic offshore locations as breeding places for the Great Auk were:
1) Rocks in a cluster about 20 miles of the Reykianes Peninsula in southwest Iceland, among them Eldey Rock and Geirfuglasker.
This was the principal location for the Great Auk in Iceland.
Geirfuglasker, where most of the Great Auks bred, disappeared under the sea in 1830 during a volcanic cataclysm resulting from an earthquake.
Birds moved to Eldey Rock when their ancestral home sank. It was there, on Eldey, where the last of the world's Great Auks were killed, a pair o June 3, 1844. Eldey, unfortunately, was more accessible to men than Geirfuglasku had been.
2) the Westmann Islands (Vestmannaeyjar), off south-central Iceland. Even though the Great Auk was documented as occurring there, any evidence of their breeding came through local tradition.
It is believed that a pair of Great Auks only laid one egg a year. Thus they reproduced rather slowly.
As men appeared in the areas where they bred, the population of the Great Auk rapidly dwindled.
In North America, the species became extinct between 1800 and 1825.
It became extinct in the Faroe Islands by about 1800, in the Orkney Islands by 1811, in Greenland by 1815, and on the island of St. Kilda by 1821.
As the Icelandic population of the Great Auk shrank, birds were killed and skins sold to collectors and natural science museums.
27 Great Auks were killed in the area of Geirfuglasker in 1830-31. 10 were killed on nearby skerries from then until 1841,
During the 20th Century, in 1955, the Icelandic Museum of Natural history in Reykjavik, obtained a Great Auk skeleton - one of only 10 such skeletons in existence. The bones were collected in 1908 on Funk Island, where there once had been a large Great Auk colony.
Also at the Icelandic Museum of Natural History, there is a stuffed Great Auk. It was bought at an auction in London in 1971.
It had been a skin that was in a collection in Denmark, obtained during a trip to Iceland in 1821.
The Great Auk was closely related to another alcid that is not flightless and is still with us today, the Razorbill.
With the scientific name "Pinguins" lasting forever, the Great Auk was a northern counterpart of the "penguin" of the Southern Hemisphere.
The Great Auk was not as much of an Arctic bird as some penguins are of the Antarctic. But the evolutionary histories of the Great Auk and the penguins appear to be rather similar.
Had the Great Auk continued to survive, it would have been interesting to compare the behavior of the species.
143 PASSENGER PIGEON ______ J
144 CAROLINA PARAKEET ______ B
145 IMPERIAL WOODPECKER ______ (was in Mexico)
The IMPERIAL WOODPECKER is referred to in the narrative below, relating to the IVORY-BILLED WOODPECKER.
146 IVORY-BILLED WOODPECKER ______ (was in the southern United States)
American Birding Association (ABA) has determined that reports of the Ivory-billed
Woodpeckers in the US in the early 21st Century were not supported by any
verifiable evidence (such as photographs, audio recordings, and specimens).
The last verifiable evidence for the occurrence of the Ivory-billed Woodpecker in North America is from James Tanner's research in the late 1930s. Many specimens and a few photographs and audio recordings predate Tanner's work.
Recent DNA evidence (published in 2006) indicates that what has been said to be a subspecies of the Ivory-billed Woodpecker in Cuba, Campephilus (principalis) bairdii, was not.
First described in 1863 as a separate species, the Cuban bird has been shown to be a species more closely related to the Imperial Woodpecker of Mexico than to the Ivory-billed Woodpecker of the southeastern United States.
By that year (2006), it may well have been that all 3 of those woodpeckers had become extinct.
As to habitat, the Ivory-billed Woodpecker of the US has been (or was) in mature lowland hardwood forest, usually by water. The Cuban Ivory-billed Woodpecker has been (was) in mature lowland hardwood and hill pine forests. The Imperial Woodpecker in Mexico occurred in pine forests in hills and mountains.
In recent study, dating analyses reveal that the American & the Cuban Ivory-billed Woodpeckers and the Imperial Woodpecker diverged sometime in the mid-Pleistocene.
A sea-level difference at that time of more than 30 meters (90 feet) would have increased the size of the Yucatan Peninsula and reduced the current distance between the Yucatan Peninsula and Cuba, and thus, could possibly, have favored colonization of Cuba by a woodpecker presumably averse to flying over water.
147 BACHMAN'S WARBLER ______ (has been in the southeast USA & Cuba)
The Bachman's Warbler occurred as a breeder in the southeast US. During its non-breeding season the bird resided in Cuba.
The last definitive occurrence of a Bachman's Warbler was a multiple-observer sighting near the I'On Swamp in South Carolina in the spring of 1962.
Later, in 1977 & 1978, two sightings were reported in South Carolina and one in Louisiana. Unfortunately, those reports in the late 1970s were unsubstantiated.
Subsequent searches revealed nothing. None were found during a systematic survey, conducted by the US Fish & Wildlife Service in 2002 at the Congaree Swamp Wildlife Refuge in South Carolina, after reports the previous two years of the bird possibly being there.
As a winter visitor in Cuba, the Bachman's Warbler was last recorded in 1964.
