The rebound of the Eastern Bluebird population can be credited to the efforts of wildlife enthusiasts who worked to create habitats attractive to the remaining birds. In 1978, the North American Bluebird Society was formed to encourage the installation of nest boxes. This extensive effort provided sufficient nesting locations for bluebirds as the species competes with other cavity nesters (swallows, chickadees, wrens, house sparrows, starlings) for nesting sites.

The efforts were so successful that the Eastern Bluebird was removed from the rare species list in 1996.
Bluebirds prefer to nest in open fields, meadows, hedges or gardens. Several metro parks in the Columbus area (like Sharon Woods Metro Park) have numerous nesting boxes in fields. The bluebirds can often be found perched on the boxes, on plants in the fields or on tree limbs adjacent to the fields.
