Scientific Name: Euphagus cyanocephalus

Residency: Year-round in northern Arizona. Winter in southern Arizona.

Diet: Feeds on the ground, primarily on insects, weed seeds, grain, and small fruits.

Predators:  Coyote, Bobcat, Great Horned Owl, and Bull Snakes prey upon nests.  Sharp-shinned Hawk, American Kestrel and Great Horned Owl prey upon adults.

Nesting: The female builds a cup nest, either just above the ground (in a shrub or small tree) or directly on the ground. She lays 1-2 broods per year, 3-7 eggs each. The eggs are gray with brown markings. Brewer?s blackbirds often nest in small colonies of up to twenty pairs.

Notes: Often associates with other blackbirds, starlings, and Brown-headed Cowbirds, forming huge winter migration flocks. Taking advantage of human modifications, the Brewer?s Blackbird is common in agricultural environments and urban parks.
