Corvus corax
The Northern Raven (Corvus corax), also known as the Common Raven, is a large, all-black passerine bird with a wide distribution across the Northern Hemisphere. It is among the largest of the corvids and is recognized for its intelligence and adaptability. These birds have coexisted with humans for millennia, often appearing in folklore and mythology.

Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
A large, entirely black bird with iridescent plumage that can show blue or purple sheens in sunlight.
Features a large, thick, and slightly curved black bill.
Its tail is wedge-shaped, particularly noticeable in flight, distinguishing it from other corvids.
Possesses shaggy, elongated feathers on its throat, often called 'hackles'.
02 / A place in the world
Northern Ravens inhabit diverse environments, from Arctic tundra and temperate forests to deserts and coastal cliffs. They prefer contoured landscapes and can be found in mountainous regions, wooded areas near open land, and even urban settings where food is available.
This species has the most extensive range of any corvid, found across North America, Europe, Asia, and parts of North Africa. Its distribution extends from the Arctic Circle south to Nicaragua in the New World and to the Himalayas and northwestern India in the Old World.
Northern Ravens are generally resident throughout their range. While they do not undertake long migrations, young birds may disperse locally, and populations at the edges of their distribution might make shorter seasonal movements to avoid extreme weather.
03 / Listen a little closer
Their vocalizations are varied and complex, including a deep, resonant croak. They can produce a wide array of sounds, such as knocking, rattling, and even mimicry of other animals and human speech.
04 / The life behind the feathers
An omnivorous and opportunistic feeder, the Northern Raven consumes a wide variety of foods. Its diet includes carrion, insects, grains, berries, fruits, small mammals, birds, eggs, and food waste.
Ravens forage on the ground and are known to scavenge at carcasses, sometimes even before larger predators. They also hunt small prey and will cache surplus food in various locations like moss, snow, or leaves for later consumption, demonstrating advanced memory.
Nesting occurs from mid-February to late May, with females laying 3-7 eggs. Nests are bulky structures made primarily of sticks, often lined with softer materials like mud, fur, or grass, and are typically built on cliff ledges, in tall trees, or on human-made structures.
Northern Ravens are highly intelligent birds, known for their problem-solving abilities and complex social dynamics. They often form long-term pair bonds and defend territories, though non-breeding individuals may gather in communal roosts. They engage in playful aerial acrobatics, including dives and tumbles.
One more reason to pay attention
Northern Ravens are considered one of the most intelligent birds, capable of solving complex puzzles and recognizing individual humans.
They are the largest passerine (songbird) in the world and the heaviest, with some individuals weighing up to 2 kg.
Ravens often interact with large predators, sometimes calling them to carcasses to gain access to meat that the predators tear open.
05 / An eye for the difference
Ravens are significantly larger with a heavier bill, shaggy throat feathers, and a wedge-shaped tail, while crows have a more fanned or squared tail.
The Chihuahuan Raven is generally smaller with a less robust bill and lacks the prominent shaggy throat feathers of the Northern Raven.
Found in Europe, the Carrion Crow is smaller than the Northern Raven and has different wing and tail shapes.
