Corvus corax
A hawk-sized black corvid with a heavy bill, shaggy throat, and a wedge-shaped tail in flight.

Much larger and bulkier than a crow, approaching a Red-tailed Hawk in size
Thick, deep bill with bristly feathers over the base and a shaggy 'beard' of throat hackles
Tail tapers to a central point — a wedge or diamond shape in flight
Forests, mountains, coasts, and deserts, and increasingly cities and towns across its wide range.
Soars and glides like a raptor, with rolls and tumbles, and travels in pairs more often than crowds. The call is a deep, hoarse, croaking gronk that carries a long way.
American crows are smaller and slimmer, with an even, fan-shaped tail, a smooth throat, and a flat caw instead of a croak.
Give nest cliffs and nest trees a wide berth, and keep food packed away — ravens learn quickly around people.
Ravens pose no real danger to people, but never handle a sick or dead bird — report unusual die-offs to local wildlife authorities.
Widespread and intelligent, ravens have recolonized parts of their historic range, though they remain sensitive to persecution in places.
