Anatomy: The Blue Jay is 10-11 inches (25.5-28 cm) long. The feathers are blue and white; they have a blue head crest and a white bar on the wing. The western North American counterpart, Steller's Jay, is 11-12 inches (28-30.5 cm) long, has a black head and crest, and lacks the white wing bars. The coloration of male and females is identical - there is no easy way to tell them apart.

Diet: Blue Jays eat other birds' eggs, acorns, fruit, nuts and insects.

Nest and Eggs: Blue Jay's nests are cups made from grass, twigs and roots. Nests are built in trees and shrubs. Females lay 3-7 green-blue eggs in each clutch (a set of eggs laid at one time).
