At a Glance

Of the birds classified as perching birds or 'songbirds,' the Common Raven is the largest, the size of a hawk. Often, its deep croaking call will alert the observer to a pair of Common Ravens soaring high overhead. An intelligent and remarkably adaptable bird, living as both a scavenger and a predator, it can survive in all seasons in surroundings as diverse as hot deserts and the High Arctic tundra. Once driven from much of its eastern range, the raven is now making a comeback.

Range & Identification

Migration & Range Maps

The Common Raven is mostly a permanent resident, but some wander in fall and winter, appearing south of the breeding range.

Description

Sexes similar — Length: 22 in–2 ft 3 in (56–69 cm); wingspan: 3 ft 10 in–3 ft 11 in (116–118 cm); weight: 1 lb 8 oz–3 lb 9 oz (689 g–1.63 kg). Much larger than crows but best known by its wedge-shaped tail, very thick bill, and shaggy throat feathers. In the Southwest, compare to Chihuahuan Raven. Size About the size of a Heron, About the size of a Mallard or Herring Gull Color Black Wing Shape Fingered, Long, Narrow Tail Shape Wedge-shaped

Songs and Calls

Deep, varied, guttural croaking; a hollow wonk-wonk. Call Pattern Flat, Simple Call Type Croak/Quack, Odd, Raucous

Habitat

Boreal and mountain forests, coastal cliffs, tundra, and desert. Can live in a vast array of habitats, from tundra above the Arctic Circle to hot desert areas of the Southwest. Often, in heavily forested areas, they may also live on prairies if suitable nest sites (such as on cliffs) exist nearby.

Behavior

Eggs

4-6, sometimes 3-7. Greenish, blotched with olive or brown. Incubation is mostly or entirely by female, about 18-21 days. Male feeds female during incubation.

Young

Both parents bring food for nestlings, and female broods them while they are small. Young leave nest about 5-6 weeks after hatching.

Feeding Behavior

Typically forages in pairs, the two birds sometimes cooperating to flush out prey. Searches for nests to eat the eggs or young birds. An opportunist, taking advantage of temporary food sources. The Common Raven does most of its feeding on the ground. Often feeds as a scavenger, searching for carrion or visiting garbage dumps. In northern Alaska (Utqiagvik) in winter, they are seen feeding at the dump under artificial lights.

Diet

Omnivorous. The Common Raven may feed on practically anything, but the majority of its diet is apparently animal matter. Feeds on a wide variety of insects, including beetles, caterpillars, and others; also rodents, lizards, frogs, and eggs and young of other birds. Regularly eats carrion and garbage.

Nesting

In courtship display, the male Common Raven soars, swoops, and tumbles in mid-air. Pair may soar high together; when perched, they touch bills, preen each other's feathers. Nest site is usually on a ledge of a rock cliff, or high in a tall tree (especially a conifer). May use the same site year after year, adding material on top of the old nest. Both sexes help build. Nest is a bulky basket of large sticks and twigs, with a deep depression in the center lined with grass, bark strips, moss, and animal hair.

Conservation

Conservation Status

The Common Raven disappeared from much of the eastern and midwestern United States before 1900. In recent decades, they have been expanding their range again, especially in the Northeast, spreading south into formerly occupied areas. Change in Abundance Over Time Drawing on more than a century of community science from the Christmas Bird Count (CBC), this chart shows how this species’ relative abundance has shifted in recent decades. Explore more and get involved in the CBC.

Climate Map

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect the range of the Common Raven. Learn even more in Audubon’s Survival By Degrees project.
