Northern Raven

The Northern (Common) Raven is the largest member of the passerine order, a massive, all-black corvid with an imposing presence. It has a heavy, deep bill, shaggy "hackle" feathers on the throat that it can raise, and glossy black plumage with an iridescent purple-green sheen.

Ravens are powerful, agile fliers, often performing acrobatic rolls and dives, and are among the most cognitively sophisticated birds known, exhibiting complex problem-solving and social behavior.

They occupy an enormous geographic and elevational range, from Arctic tundra to desert canyons to high mountains, across most of the Northern Hemisphere.

Key field marks

• Very large size, clearly bigger than any crow
• Massive, deep-based bill
• Shaggy throat feathers (hackles), especially visible when calling
• Wedge-shaped or diamond-shaped tail in flight, versus the crow's fan-shaped tail
• Deep, resonant croaking call

Similar species

• Carrion Crow / Hooded Crow: much smaller, with a slimmer bill, smooth throat feathering, and a squared or rounded tail in flight
• Rook: smaller still, with a bare pale face patch and social flocking habits

Behavior cues

Ravens are usually seen alone or in pairs soaring on flat wings with frequent glides, unlike the more flapping flight of crows; the wedge-shaped tail is often the best flight-silhouette clue.

Habitat

Extremely adaptable, found in mountains, coniferous and mixed forests, coastal cliffs, tundra, grasslands, and deserts.

Range

One of the most widely distributed birds in the world, occurring across North America, Europe, North Africa, and Asia — essentially circumpolar across the Northern Hemisphere.

Migration

Largely resident and territorial year-round, though young, non-breeding birds may wander widely or form nomadic flocks before establishing territories.

Behavior

Ravens are highly intelligent, forming long-term pair bonds and defending large territories. They are known for playful behavior, including aerial acrobatics, and for sophisticated problem-solving, tool use, and caching of food with apparent awareness of being watched by rivals.

Voice

A deep, resonant "gronk" or croaking call, along with a wide repertoire of other sounds including knocks, rattles, and even mimicked noises.

Feeding

An opportunistic omnivore and scavenger, eating carrion, small mammals, birds, eggs, insects, and grain, and often the first scavenger to find large carcasses.

Nesting and breeding

Builds a large stick nest on a cliff ledge, in a tall tree, or on a human structure, reused and added to over multiple years. Clutches typically contain 3–7 eggs, incubated by the female.
