American Crow vs Common Raven (Corvus brachyrhynchos vs Corvus corax): The Complete Backyard Identification Guide
Field Summary
Quick Answer: The Fastest Way to Tell Them Apart
The classic big-black-bird problem. Three rules that work at any distance:
- Size: ravens are enormous — buzzard-sized, half again the crow’s length and more than twice its weight. If it looks hawk-big, think raven.
- Tail in flight: crow’s tail is a squared-off fan; the raven’s tail comes to a clear wedge or diamond point.
- Voice: a clear, familiar “caw-caw” = crow; a deep, guttural croak — “kraa” or “gronk” — = raven.
At-a-Glance Comparison Table
Crow vs raven, side by side. KEY rows separate fastest.
| Feature | American Crow | Common Raven |
|---|---|---|
| Scientific Name | Corvus brachyrhynchos | Corvus corax |
| Length KEY | 17.5 in (45 cm) | 24–27 in (61–69 cm) |
| Wingspan | 36–39 in (91–100 cm) | 45–51 in (115–130 cm) |
| Weight KEY | 11–21 oz (320–600 g) | 1.5–4.4 lb (0.7–2.0 kg) |
| Overall Shape | Large all-black songbird with a fan-shaped tail | Huge all-black corvid with a wedge-shaped tail |
| Male Plumage | Entirely black with a slight gloss; stout black bill (sexes alike) | Entirely black, glossy, with shaggy throat feathers and a massive bill (sexes alike) |
| Female Plumage | Identical to the male, averaging slightly smaller | Identical to the male, averaging smaller |
| Bill Shape | Stout, straight, all-black bill | Massive, heavy, slightly curved black bill |
| Tail KEY | Squared to slightly rounded fan tail | Distinctly wedge-shaped in flight |
| Core Range KEY | Nearly the entire US and southern Canada; cities, farms, woods and shores | Mountains, deserts and forests of the West and far North; expanding east |
| Migration | Mostly resident; northern birds shift south in winter roosts | Non-migratory |
| Feeder Presence | Takes cracked corn, peanuts, eggs and table scraps from platforms | Rare at feeders; visits rural platforms for meat scraps, eggs and carrion |
| Favorite Foods | Omnivore: grain, insects, carrion, eggs, fruit, refuse | Carrion, small animals, grain, fruit, refuse |
| Song KEY | The familiar loud “caw-caw-caw” | A deep, resonant “kraaak” and an astonishing range of croaks and knocks |
| Flight Call | Varied caws; also rattles and knocks | Deep croaks far lower than any crow |
| Population Trend | Common and adaptable; numbers fluctuate with West Nile virus cycles | Stable and expanding into new areas |
Male Field Marks, Side by Side
American Crow — Male
Corvus brachyrhynchos

- Familiar loud “caw-caw”.
Common Raven — Male
Corvus corax
- Twice the bulk of a crow; wedge tail in flight.
- Shaggy throat hackles; massive bill.
- Soars like a hawk — crows rarely soar.
Female & Juvenile Marks, Side by Side
American Crow — Female
Corvus brachyrhynchos
- Identical to the male.
- Family groups cooperatively raise young.
- Gathers in huge winter roosts.
Common Raven — Female
Corvus corax
- Identical to the male.
- Pairs mate for life and soar together.
- Deep croaking calls carry for a mile.
Part-by-Part Anatomy Breakdown
Silhouette does the work — size, tail and throat before plumage details:
| Body Part | American Crow | Common Raven |
|---|---|---|
| Size | Crow-sized, 17.5 in | Buzzard-sized, 24–27 in |
| Tail in Flight | Squared to slightly rounded fan | Wedge or diamond shape |
| Throat | Smooth feathers | Shaggy, elongated hackles |
| Bill | Stout but proportional | Massive, heavy, strongly curved |
| Wings | Shorter, blunter | Longer, narrower, more fingered |
| Flight | Steady rowing wingbeats, little soaring | Frequent soaring; rolls and dives in display |
| Head | Smooth crown | Heavier brow and bill give a Roman-nosed profile |
Song & Call Comparison

Range & Seasonal Presence
The American Crow thrives nearly everywhere people do — cities, farms, suburbs, woodlots — across almost all of the US and southern Canada.
The Common Raven is the bird of wilder country: mountains, deserts, forests and coasts of the West and North. It is now re-expanding into the East — ravens are increasingly regular in Appalachia and even on the edges of eastern cities, so range alone is no longer a safe rule there.
Feeder Behavior & Favorite Foods
- American Crow: a regular platform and lawn visitor for cracked corn, peanuts, eggs and scraps; learns feeding schedules quickly.
- Common Raven: less of a feeder bird but will take meat scraps, eggs and carrion from open ground near rural homes; in the West it patrols roadsides and landfills more than backyards.
- Best foods: both take meat, eggs, corn and peanuts; neither needs encouragement — secure your trash instead.
- Behavior clue at the food: crows feed in chattering groups; ravens usually arrive as a deliberate pair and work a carcass or scrap pile alone.
Temperament & Flock Behavior
American Crows are intensely social — family groups, winter roosts of thousands, and coordinated mobbing of owls and hawks.
Common Ravens travel as pairs or small family units, play in flight with barrel rolls, and are famously playful and curious — sliding down snowbanks and teasing dogs.
6-Step Backyard ID Checklist
- Size first. Hawk- or buzzard-sized = raven; crow-sized = crow.
- Tail shape in flight. Squared fan = crow; wedge or diamond = raven.
- Voice. Clear “caw” = crow; deep croaking “kraa” or “gronk” = raven.
- Throat. Shaggy hackles when perched = raven; smooth throat = crow.
- Flight style. Constant rowing wingbeats = crow; soaring with acrobatic rolls = raven.
- Social setting. Noisy group in town = crows; a deliberate pair over wild country = ravens.
Frequently Asked Questions
How do you tell a crow from a raven?
Ravens are much larger — buzzard-sized — with a wedge-shaped tail, shaggy throat feathers, a massive bill and a deep croaking call. Crows are smaller with a squared fan tail and a clear “caw”.
Which is bigger, a crow or a raven?
The Common Raven is far bigger: 24–27 inches long and two to four times the crow’s weight, versus about 17.5 inches for an American Crow.
Do crows and ravens live in the same places?
Increasingly, yes. Crows favor cities and farmland everywhere; ravens favor wild country in the West and North but are re-expanding into the East and now appear near towns and even cities.
What does a raven sound like compared to a crow?
The crow’s call is the familiar clear “caw-caw”. The raven gives a much deeper, guttural croak — “kraa” or “gronk” — plus clicks, knocks and bell-like notes.
Are ravens or crows smarter?
Both are among the most intelligent birds on Earth. Crows excel at recognizing human faces and using tools; ravens show planning, play and problem-solving that rival great apes in some tests.
Do ravens come to bird feeders?
Rarely for seed, but rural ravens will take meat scraps, eggs and carrion from open ground. Crows are the dependable backyard scavengers of the two.
