Poet Henry David Thoreau wrote that the bluebird “carries the sky on its back.” The first warm days of late winter and early spring send Thoreau’s bits of sky looking for a place to nest. Eastern bluebirds once made their homes in tree cavities. Lacking good nesting spots these days, bluebirds have come to rely on nest boxes specially designed for them. A bluebird box placed by March can raise as many as three broods by summer’s end. In fourteen days, the eggs hatch and in another couple of weeks, the young are ready to fly from the box.
Bluebirds are rural birds, seen in open grasslands with scattered trees or fences. They’re more abundant thanks to people putting up nest boxes for Missouri’s state bird that carries the “sky on its back.”
