Bluebird Identification

Western Bluebirds, Mountain Bluebirds, and Eastern Bluebirds are a hue of blue seen nowhere else in nature.

The bluebird is a member of the thrush family, and they lay four to six pale blue eggs in a grass nest set in a hollow tree or woodpecker hole. By looking at a male Western Bluebird through good bird watching binoculars, you may observe that he has a crescent mark across his upper back. Bluebirds are, however, extremely shy of humans and protective of their young. At American Bird Guide, we have found the bluebirds' favorite hunting ground to be a vineyard adjacent to our property. This vineyard is surrounded by old trees which, no doubt, provide excellent nesting sites.

The western United States also plays host to the Mountain Bluebird, which can be slightly larger than the Western Bluebird. Male Mountain Bluebirds are more of a turquoise blue above with a light blue breast and white belly. They have a warbling song, and prefer to live in mountain meadows. Mountain Bluebirds are expert insect catchers.
