Anatomy: The Eastern Bluebird is about 5.5 to 7 inches (14-18 cm) long and has a wingspread of 11 to 13 inches (28-33 cm). The bill is thin. Males have bright blue feathers above, an orange-red throat and breast, and a white belly. Females are camouflaged; they have dull blue wings and tail, a gray head and back, a brown breast, a white eye ring, and a white belly.

Diet: The Eastern Bluebird mostly eats insects (especially grasshoppers, crickets, katydids, and beetles), worms, snails, and spiders; it also eats fruit.

Nest and Eggs: Eastern Bluebird nests are cup-like and are made from dried grass, pine needles, and plant stems. Nests are built in holes in trees and rotted tree stumps. Females lay 3-6 pale blue eggs in each clutch (a set of eggs laid at one time). The female incubates the eggs for 12-14 days. Both parents care for the hatchlings for 15-20 days, when the young leave the nest.
