Birds sometimes that are common some places are rare others.
The Blue Jay, common in eastern North America, just reaches eastern
Colorado.
Actually, although our Colorado in April Tour is primarily for Grouse,
it is also a good one for corvids, with 10 species in that family of jays
& crows.
In addition to the Blue Jay, other corvids that we see in Colorado include:
Steller's Jay, Western Scrub-Jay, Pinyon Jay, Gray Jay,
Clark's Nutcracker, Black-billed Magpie,
Common Raven, Chihuauan Raven, and American Crow.
