Carrion Crow

The Carrion Crow is a large, entirely black corvid with a glossy purplish-green sheen on fresh plumage. It has a heavy, straight black bill, black legs, and an all-black iris, giving it a uniformly dark appearance from bill to tail.

Unlike its highly social relatives the Rook and Jackdaw, the Carrion Crow is typically encountered singly, in pairs, or in small family groups, defending territories year-round.

It is one of the most intelligent and adaptable birds in its range, thriving in habitats from remote farmland to city centers.

Key field marks

• Entirely glossy black plumage, bill, and legs
• Straight, evenly proportioned black bill (culmen not strongly arched)
• Rounded crown profile, no bare facial skin
• Solitary or paired habits rather than large flocks

Similar species

• Rook: has a bare pale face patch (adults), peaked crown, and shaggy thighs, and is far more social
• Hooded Crow: has grey body plumage with only the head, wings, and tail black — the two forms hybridize where their ranges meet
• Raven: much larger, with a heavier bill, shaggy throat feathers, and a wedge-shaped tail in flight

Behavior cues

A single crow or pair walking purposefully across a field, mobbing a raptor, or perched alone atop a tree is more likely a Carrion Crow than the flock-forming Rook.

Habitat

Highly adaptable, occupying farmland, woodland edges, moorland, coastlines, and urban and suburban environments including parks and gardens.

Range

Found across western Europe and east across Asia, with the Hooded Crow replacing it through much of central, northern, and eastern Europe and the Middle East; the two forms interbreed in a narrow hybrid zone.

Migration

Largely resident and sedentary, defending the same territory throughout the year, though some northern birds may disperse locally in harsh winters.

Behavior

Carrion Crows are territorial and typically live in pairs that mate for life, though non-breeding immatures may form loose flocks. They are famed for their intelligence, using tools in some populations and remembering human faces.

Voice

A harsh, resonant "caw-caw-caw," usually given in a short series, deeper and more deliberate than the Rook's flatter call.

Feeding

An opportunistic omnivore and scavenger, taking carrion, insects, small vertebrates, eggs, nestlings, grain, and human food waste.

Nesting and breeding

Builds a solid stick nest lined with softer material, usually in a tall tree or occasionally on a cliff or pylon. Clutches typically hold 3–5 eggs, incubated by the female.
