You’re outside, enjoying a sunny day when a shadow at your feet causes you to look up. A large, black bird flies over and lands in a nearby tree. You wonder: is that a crow or a raven?
These two species, common ravens and American crows, overlap widely throughout North America, and they look quite similar. But with a bit of practice, you can tell them apart.
You probably know that ravens are larger, the size of a red-tailed hawk. Ravens often travel in pairs, while crows are seen in larger groups. Also, watch the bird’s tail as it flies overhead. The crow’s tail feathers are basically the same length, so when the bird spreads its tail, it opens like a fan. Ravens, however, have longer middle feathers in their tails, so their tail appears wedge-shaped when open.
Listen closely to the birds’ calls. Crows give a cawing sound. But ravens produce a lower croaking sound.
We’re back looking up at that tree. Now can you tell? Is this an American crow or a common raven?
That’s a raven. The bird calls you hear on BirdNote come from the Macaulay Library at the Cornell Lab of Ornithology. To hear them again, begin with a visit to our website, BirdNote.org. I’m Michael Stein.
