The population of the Eastern Bluebird declined seriously enough in the past century to reach critical status by the mid-1900s. The decline was due to: 1. Habitat destruction (loss of fields and nesting cavities in split-rail fences; clearing of dead trees) 2. Nest predation by House Sparrows and European Starlings; both of which are non-native, introduced species. More

Eastern bluebirds often nests in woodpecker-excavated cavities. The nests are built using grasses, weed stems, pine needles, twigs, and occasionally hair or feathers. The nest is built in an average of 10 to 11 days both by male and female. Pairs begin nesting by choosing a natural cavity or an abandoned woodpecker hole in a post or tree, or perhaps a man-made nesting box. Bluebirds nest March through August. Female birds lay about 3 to 7 eggs, occasionally white and unmarked with 0. More

The ongoing recovery of the eastern bluebird is an example of how sound wildlife management practices have been used to increase the survival success of an individual wildlife species. This pamphlet is designed to serve as an introduction to the habitat requirements of the eastern bluebird and to assist in the development of a comprehensive bluebird management plan. More

Place eastern bluebird nest boxes in open grassy areas that are accompanied by widely scattered trees and shrubs. Open areas are preferred, as placement of boxes in or near areas thick with brush and woody vegetation likely will result in habitation of many boxes by house wrens. Boxes should be placed at least 100 yards apart to accommodate individual territories established by nesting pairs during the breeding season. More

The eastern bluebird is a favorite migratory songbird of birders and nonbirders alike. The bird's bright blue color and melodious song make it a welcome visitor to backyards.

During the days of frontier settlement, the bluebird was among the wildlife species that benefited from the decimation of the eastern forests. More

The Eastern Bluebird, a member of the Thrush family and one of three species of bluebirds that occur in North America, is a cavity nester that lives in open country. They occur in the eastern half of North America as far west as the Rocky Mountains, and as far south as Nicaragua. Populations have suffered since these birds must compete with House Sparrows, Starlings, woodpeckers and other cavity nesters. Placement of nest boxes for Bluebirds has resulted in population increases in many regions. More
