About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
Black-billed Magpie
The Black-billed Magpie is a striking, long-tailed corvid of western North America, with bold black-and-white plumage and an iridescent blue-green sheen on the wings and tail. It inhabits open country with scattered trees, riparian woodlands, and suburban areas from Alaska south to California and east to the Great Plains. It is omnivorous, feeding on carrion, insects, fruits, seeds, and small vertebrates.
