American Crow

The American Crow is a large, entirely glossy black bird with a stout bill, black legs, and dark eyes, found across nearly all of North America. It is one of the most familiar and widespread birds on the continent, thriving in habitats ranging from farmland and forest edges to city parks and parking lots.

Crows are renowned for their intelligence, exhibiting tool use, problem-solving abilities, and complex social structures, including the recognition of individual human faces. They live in extended family groups, with young from previous years often remaining with their parents to help raise subsequent broods.

Key Field Marks

• Entirely glossy black plumage, including bill, legs, and eyes
• Stout, straight bill
• Fan-shaped tail in flight, with steady, direct wingbeats
• Large size compared to blackbirds and grackles

Similar Species

• Common Raven is noticeably larger with a heavier, curved bill, a wedge-shaped tail in flight, and a deeper, croaking voice compared to the crow's higher-pitched caw.
• Fish Crow is nearly identical in appearance but smaller, with a distinctive nasal, two-syllable uh-uh call, and is restricted to coastal and riverine areas of the eastern and southeastern United States.
• Chihuahuan Raven shows white feather bases on the neck (visible when wind ruffles feathers) and inhabits arid Southwest grasslands.

Habitat

American Crows are highly adaptable, occupying farmland, open woodlands, forest edges, city parks, suburban neighborhoods, and landfills.

Range

This species is found across nearly all of the contiguous United States and southern Canada, with populations extending into northern Mexico.

Migration

Northern populations migrate south for winter, often forming enormous communal roosts of thousands to millions of birds, while southern populations are largely resident year-round.

Behavior

American Crows are highly social, living in family groups and often gathering in large winter roosts. They are known for cooperative breeding, mobbing predators such as hawks and owls, and sophisticated problem-solving, including using tools and remembering human faces for years.

Voice

The familiar call is a loud, harsh caw-caw-caw, with a wide repertoire of other calls used for different social contexts, including rattles, coos, and clicks.

Feeding

Crows are opportunistic omnivores, eating insects, earthworms, small vertebrates, eggs, seeds, fruit, carrion, and human food waste; they often cache food for later use.

Nesting

Pairs build a bulky stick nest high in a tree, often aided by non-breeding helpers from previous broods; the female incubates 3-9 blue-green, brown-spotted eggs while the group defends the nest.
