Pied Crow As the term suggests, pied crows have a large strip of white feathers separating their blackhead and lower breast. In addition, they have a wingspan of about 95- 105 cm. Now it’s time to get out there and do a bit of bird watching to see if you can tell the difference between the crow and the raven. A healthy carrion crow weighs 0.3 to 0.7 kg and measures 46-48 cm long. Ravens’ feathers are sleek and shiny, and their wings have a blue/purple tint in the sun. However, crows’ feathers are a bit more dull with wings that have a purple/green tint to them in the sun. Ravens have large, curved bills with a nice big tuft of feathers right on the top.ĬOLOR Both are black – one of the reasons it’s hard to tell them apart. Ravens would rather soar on air currents called thermals with their wingtips extended like fingers.īILLS Crows have smaller bills with a small tuft of feathers on the top. However, ravens eat more meat than crows, while our crows seem just as happy with leftover French fries or the peanuts from our feeder.įLIGHT Crows flap their wings more while in flight. Both will hunt for bugs and small animals and snatch eggs out of nests. Both will scavenge for garbage and carrion (dead animals). Ravens like the wilder, remote, quiet abodes.įOOD Crows and ravens are omnivorous, that means they eat plants and animals. HOME GROUND Crows are more at home in cities and places where people call home. Crows call out to others when they find a good food source. They are also comfortable alone, with a mate, or small groups too. SOCIAL STUDIES Crows are more social and tend to “hang with the crowd”. Plus, studies have shown that crows have up to 250 different variations of their sounds! Ravens have more of a croaking sound, almost like a sheep with a sore throat. as the Common Raven are mobbed as they pose a threat to Hooded Crows. VOICE Yes, they do talk differently! Crows make the recognizable “caw, caw, caw” sound. The Hooded Crow (Corvus cornix) is a widely distributed Eurasian bird species. Their wingspan is 3-4 feet, and they weigh 1.5 to 4.4 pounds. Their wingspan is 2-3 feet, and they weigh 7-14 pounds. ![]() A team of researchers at the University of Washington ran an experiment where they captured American Crows in nets while wearing a caveman mask, then released them back onto campus. That’s probably for the best, because crow communities can hold a grudge for generations. Here are some of the ways to tell them apart.

Crows and ravens are in fact two different species of birds. A genus is a group of animals containing similar types. ![]() They do look alike and belong to the same genus called Corvus. But are they crows or are they ravens? Let’s learn the difference. We get them here very often at our bird feeders. Crows, you’ve seen them, big black birds flying through the sky.
