Despite the name 'bluebird house', eastern bluebirds are not the only species that call those little wooden boxes home. Bluebird houses (hereafter called bluebird nest boxes) are also used by tree swallows, chickadees, house wrens, and house sparrows. All of the aforementioned species are cavity nesters, meaning they build their nests in cavities, whether naturally occurring (in trees) or man-made (in nest boxes).
