Quick answer
Ravens are noticeably larger than crows, with a wedge-shaped (diamond) tail, shaggy throat feathers, and a deep, hollow croaking call. Crows are smaller with a fan-shaped tail, smooth throats, and a sharper, higher-pitched "caw." In flight, ravens mix soaring and gliding with their wingbeats; crows flap more steadily.
Six ways to tell them apart
1. Tail shape in flight (the most reliable tell)
Watch the tail as the bird flies overhead or away from you. A raven's tail comes to a distinct point — a wedge or diamond shape. A crow's tail spreads into a rounded fan or a squared-off edge. This works even at distance and is the quickest field mark when the birds are moving.
2. Size
A raven is substantially larger — roughly buzzard-sized, measuring 54–67 cm from bill to tail. A carrion crow is closer to a pigeon or a small chicken at 45–52 cm. The difference is noticeable when they are side by side, but harder to judge alone. Context clues (sitting on a fence post, flying near buildings) help calibrate size.
3. Throat feathers
When perched, look at the throat. A raven has distinctly ruffled, elongated "hackle" feathers around the throat and upper breast that stick out when it calls or displays, giving a shaggy or bristled look. A crow has flat, smooth feathers in the same area with no ruffling.
4. Call
The calls are markedly different once you know them. A raven gives a deep, resonant "kronk" or hollow croaking sound — almost like a sound effect from a dungeon. A crow gives a brisk, nasal "caw" that is sharper and higher. If you can hear it, the call alone usually settles the question.
5. Bill size
A raven's bill is larger and heavier, with a more pronounced curve at the tip. A crow's bill is more slender and straight. This is easier to see in a good photo or at close range than from a distance.
6. Flight style
Ravens frequently soar and glide, circling on thermals the way a buzzard or eagle might. Crows flap more steadily and purposefully, with occasional short glides. If a large black bird is lazily soaring in circles, it is more likely to be a raven.

Intelligence: both exceptional
Crows and ravens are both considered among the most cognitively advanced birds known to science. Crows have been documented using tools — selecting and modifying twigs to retrieve food from holes — and can remember the faces of specific humans for years. American crows have been recorded dropping nuts onto roads for cars to crack, then waiting for the pedestrian crossing signal before retrieving them.
Ravens have demonstrated forward planning, trading tokens for future rewards, and an understanding of other ravens' likely actions (a cognitive ability once considered limited to great apes). In Scandinavia and Iceland, ravens have been observed following wolves on hunts to feed on their kills, and are believed to alert wolves to carcasses they cannot open alone.
Crow vs raven: FAQs
What is the simplest way to tell a crow from a raven?
Tail shape in flight: a crow's tail fans out in a rounded or squared shape; a raven's tail forms a distinct wedge or diamond point. Size also helps — a raven is noticeably bigger, roughly the size of a buzzard, while a crow is more pigeon-sized.
What do ravens sound like versus crows?
Ravens give a deep, resonant 'kronk' or hollow croaking call. Crows have a higher-pitched 'caw' that is sharper and more nasal. The raven's call sounds almost ancient or reverberating compared to the brisk caw of a crow.
Are ravens just big crows?
They are both members of the corvid family (Corvidae) and share the genus Corvus, but they are separate species with distinct behaviours, calls, and structures. Ravens are substantially larger, with a longer bill, shaggy throat feathers, and a wedge-shaped tail — not just scaled-up crows.
Which is smarter — crow or raven?
Both are among the most cognitively advanced birds known. Ravens have shown impressive problem-solving, planning, and social cognition — including the ability to understand other ravens' intentions. Crows are famous for tool use and memory, including recognising specific human faces. Both species are studied as examples of avian intelligence at the highest level.
Do crows and ravens live in the same places?
They often share overlapping ranges, including much of the UK, Europe, and North America. However, ravens tend to prefer wilder, more remote areas — moorland, mountains, sea cliffs, and ancient woodland — while carrion crows are more adaptable and common in farmland, parks, and suburban areas.
What are the shaggy throat feathers on a raven?
Ravens have elongated, lanceolate (spear-shaped) feathers around the throat and upper chest that give a distinctly ruffled or shaggy appearance when the bird calls or displays. Crows have smooth, flat feathers in the same area. The shaggy throat is one of the most reliable field marks when the birds are perched.
