Blue Jay

Order: Passeriformes

Family: Corvidae

Genus: Cyanocitta

Species: C. cristata

General Characteristics: The blue jay is between 9 and 12 inches long. It is bright blue on top and white to gray on its throat, chest and belly. It has a gray-blue crest on its head and black and white bars on its wings and tail. Its bill, legs and feet are black. It also has a black "necklace" on its lower throat. The blue jay is omnivorous. It eats fruits, acorns, seeds, nuts, insects, mice and frogs. Sometimes a blue jay will raid a nest for eggs and young birds. When a blue jay eats nuts, it holds the nut with its feet and cracks it open with its bill. The blue jay is a seed spreader. It often buries food to eat later.

Special Characteristics: Blue Jays are known to take and eat eggs and nestlings of other birds, but we don’t know how common this is. In an extensive study of Blue Jay feeding habits, only 1% of jays had evidence of eggs or birds in their stomachs. Most of their diet was composed of insects and nuts.
