Conservation status	In the past, declined seriously in many areas with loss of habitat and loss of nesting sites. During recent decades has been increasing again, undoubtedly helped by birdhouses in many areas.
Family	Thrushes
Habitat	Open country with scattered trees; farms, roadsides. Breeds in many kinds of semi-open habitats, including cut-over or burned areas, forest clearings, farm country, open pine woods; locally in suburbs where there are extensive lawns and good nest sites. Wanders to other habitats in winter.

This is the most widespread of the three bluebirds. Although it is mostly "eastern" in our area, its total range extends south to Nicaragua. A high percentage of Eastern Bluebirds in North America today nest in birdhouses put up especially for them along "bluebird trails." When they are not nesting, these birds roam the countryside in small flocks.
