Eastern bluebirds are the common bluebirds of the Central and Eastern U.S.; over the past decade, they have been observed as far west as the Colorado Front Range. In general, these attractive songbirds favor open country with scattered trees or a nearby forest edge; they are thus rather common in farm country, at conservation areas and at large parks.
Over the past several years, a small flock of eastern bluebirds have resided in our suburban neighborhood; though there are many large trees with cavities for nesting, open space is limited to modest-sized lawns. Nevertheless, they seem content to remain throughout the year, consuming a wide variety of invertebrates during the warmer months and raiding berry trees and shrubs in winter.
Perhaps the suburban life appeals to them. Whatever their sentiment may be, these quiet, peaceable and colorful birds are more than welcome in the neighborhood.
