Bluebird Facts | Barn Owl Box Company

Bluebirds begin breeding in early to late March in most areas.
Breeding begins with males staking out potential nest sites and advertising them to prospective females with display flights and calls.
Once the female chooses a site, she alone will build the nest and brood the eggs.
Nests are built with grass, hay, and pine needles with an inner liner of softer grass, hair, and feathers. Construction takes about 10 days.
Four to six powder blue eggs form each clutch.
The male provides the family with beetles, grasshoppers, crickets, and other insects as well as various berries throughout the nesting period.
Bluebird young leave the nest fully grown at 15 days and begin feeding on their own. A year later they are ready to raise young of their own.
Bluebirds can raise as many as four families a season, breeding into late summer.
Northern populations migrate in the winter; southern birds remain sedentary.
