Corvus brachyrhynchos
A glossy, pigeon-sized black bird whose rounded, fan-shaped tail is the quickest way to separate it from a raven.

All-black plumage with a slim, fairly straight bill
Tail spreads into an even, rounded fan in flight
Smooth, sleek throat without shaggy hackles
Towns, farmland, open suburbs, parks, and field edges. Large communal roosts form outside the breeding season.
Flies with steady, rowing wingbeats and rarely soars for long. Social and noisy, often in family groups or large roosts, with a flat, familiar caw-caw.
Common ravens are much larger, with a heavier bill, shaggy throat hackles, and a tail that tapers to a wedge-shaped point in flight.
Watch from a distance and let roosts settle undisturbed. Never feed crows; food-conditioned birds cause conflicts.
Crows pose no real danger to people, but never handle a sick or dead bird — report unusual die-offs to local wildlife authorities.
Abundant and adaptable across North America, though populations are affected by disease outbreaks and roost disturbance.
