American crow is the common crow over much of the U.S. and Canada. Most easily identified by voice, a familiar “caw,” often repeated. Common in any open habitats, including fields, open woodlands, marshes, and cities, thriving around humans. Very social, usually seen in flocks, sometimes numbering in the hundreds or even thousands. Aggressive, sometimes seen chasing away hawks and owls. Separated from ravens by smaller size, smaller bill, shorter tail, and shorter, broader wings.
