Common Raven vs American Crow
[science] Key marks: tail (wedge vs fan), size (raven ~twice the weight), voice (raven croaks deeply, crow caws sharply), hackles (raven has shaggy throat feathers, crow does not). In open country with both present, the size difference alone is diagnostic.
Side-by-Side Measurements
| Feature | Common Raven Corvus corax | American Crow Corvus brachyrhynchos |
|---|---|---|
| Length | 56–69 cm | 40–53 cm |
| Wingspan | 120–150 cm | 85–100 cm |
| Weight | 689–1,625 g | 316–620 g |
| Tail shape | Wedge-shaped | Fan-shaped (rounded) |
| Bill | Heavy, arched, deep | Moderate, slightly curved |
| Throat feathers | Shaggy hackles | Smooth, no hackles |
| Voice | Deep croak "kronk/pruk" | "Caw" — higher, nasal |
| Flight | Soars frequently; plays aerially | Direct flapping; occasional glide |
| Habitat preference | Wild country, coasts, mountains, some urban | Wide tolerance — suburbs, farmland, forests |
| IUCN | Least Concern (LC) | Least Concern (LC) |
Key Identification Tips for North America
- Flying overhead: check tail shape first — wedge vs fan. Then look at wing length: ravens have longer, narrower wings with more pronounced "fingers" at the tips.
- Perched bird: size, bill profile (heavy vs moderate), and throat (shaggy vs smooth).
- By ear: a deep "kronk" or "pruk" is a raven; any caw-like call is a crow. With experience, voice is one of the most reliable marks.
- Habitat context: in a city park or suburban garden, it is almost certainly a crow. On a coastal cliff or mountain ridge, it is more likely a raven.
Frequently Asked Questions
What is the easiest way to tell a raven from an American Crow?
Tail shape is the fastest mark: wedge-shaped on a raven, fan-shaped on a crow. Size is also dramatic — ravens are roughly twice the weight of American Crows. Voice: ravens croak deeply ("kronk"), crows caw sharply. All three marks together make identification straightforward in most cases.
Can ravens and American Crows live in the same area?
Yes — their ranges overlap across much of North America, particularly in the Pacific Coast states, the Intermountain West, and the northeastern US. Where they occur together, the size difference is immediately apparent.
Are American Crows and ravens in the same genus?
Yes — both are in the genus Corvus (family Corvidae). The Common Raven is Corvus corax; the American Crow is Corvus brachyrhynchos. They are closely related but are distinct species that do not hybridise.
