American Crows are familiar over much of the continent: large, intelligent, all-black birds with hoarse, cawing voices. They are common sights in treetops, fields, and roadsides, and in habitats ranging from open woods and empty beaches to town centers. They usually feed on the ground and eat almost anything—typically earthworms, insects, and other small animals, seeds, and fruit; also garbage, carrion, and chicks they rob from nests. Their flight style is unique, patient, and methodical flapping that is rarely broken up with glides.
