I observe ravens in Iceland (work there) where there the only corvid is the raven. So it's easy for me there - but here in NYC and in MA where I am a residet, I have trouble. I have spotted ravens in the city, and they are huge - I compare them with hawks for size, as they are usually about the same distance away as a hawk (far), fly in pairs, land on top of high buildings, and I've even been able to catch the "wedge-shaped" tail in a photo. There are a lot of crows in NYC and at the Cape (Cod/MA) common crows and fish crows. They are noisy and in small flocks, rarely alone. The ravens, if they call, are distinctive in their croak.

Those eyes on the grackle make it very easy to distinguish a grackle from a crow! I feel pretty good about distinguishing a raven from a crow, too, as long as I am close enough to eyeball its size! Crows are so gorgeous, and I'm not just saying that because they are in my last name! :D

The eyes and beak help me identify a crow. The Wings and tails in flight still confuses me.

Crows have dark/black eyes. Some of the other birds with which the crow is sometimes confused have yellow/light brown eyes.

Fairly confident

Yes appears to be many different things that help you distinguish the difference . Size ,color of eyes  colors on body and tail feathers / shape  beaks

Yes, for the most part. But the crows around here in the Alberta Boreal are large. I've been listening mornings to a young family of ravens (judging only by sound). The fledgelings sound like crow caws, but when the adult chimes in, it's more of a cronk. I wouldn't bet the farm on identifying by sound.

Ravens are notably larger and have pointier tales and wings as well as a longer hooked beak

Yes I feel confident in identifying crows

I do see crows regularly (lots of them) and ravens less often, but still somewhat regularly (usually just one or two at a time). The first time I saw a raven in my area he was standing among a  group of crows and seagulls that I was feeding (he was hanging back a bit). At first I thought, that's a very large crow, as body-wise he was as large as a seagull... of course it wasn't a large crow, it was a raven. I got up to speed after that in telling the difference between the two. Sometimes it's harder at a distance, unless I hear their call... that's a real give-away.

I see both crows and ravens here in N California and have now learned to tell them apart by size and tail.

Yes I can tell the difference.

I’m not sure if there are Ravens here on the Monterey Bay, but I’m going to find out and if there are I will try to identify them.

The crow's facial features like eye and beak shape are different!

We don't have ravens in North Florida, so I don't need to distinguish between crows and ravens at home, but when traveling I can usually tell them apart by size and beak shape. I didn't know that ravens have longer throat feathers and that will be helpful for close up IDs in the future. Sometimes it's challenging to distinguish crows from grackles when they're flying. We also have Fish Crows, which I can distinguish from American Crows by their call.

The beak size and shape along with the eye coloring were two of the key identifiers that I took away from this lesson.

I am getting better at noticing beak size, eye color and tail shape/size. In New Jersey there are no ravens but plenty of grackles, red wings, cow birds and starlings. In flight is my biggest challenge.

I'm confident in being able to distinguish between crows and ravens. I've only seen a raven in captivity but the size difference was amazing. I have actually heard a crow that sounded a lot like a raven. His voice was totally different from all the other crows in my area (SF Bay Area).

I m fairly confident with these pictures, but will probably have more trouble distinguishing crows from ravens in reality.

I'm fairly confident in my ability to distinguish crows from ravens. I do so mostly by their call - caw and cronk. Ravens where I live are markedly bigger than crows. I look for the scruffy neck feathers to identify the raven.

I don't have much trouble separating the crows from the grackles and blackbirds when they are perched or nearby... and none at all when they are calling. I do run into issues though when they are in flight and at a distance. Then I am more like to confuse them with the vultures (black or turkey) until they turn or glide. I don't quite have the wingbeat patterns down or the silhouettes. The very strong light in Texas can wash out a lot of the telltale details.

I noticed that the crow's eyes are black, too. That helped me distinguish between them and the other birds on some of the close-up head shots.  I had more trouble identifying them in flight from a distance or by silhouette.

I'm pretty good distinguishing crow from non-crow/raven; but between a crow and a raven in real life, not still pictures, I'm a little shaky. It doesn't help that there aren't many ravens in this area for me to practice on. I appreciate the tips from this lesson, though. I'll be sure to put them into practice when I go birding in the future.

I am confident in my ability to distinguish between crows (or ravens) and non-crows/ravens. My ability to discriminate crows from ravens when perched or on the ground is also fairly solid, less so in flight which is how we often see them here in canyon country (southeast Utah). Habitat, habits and calls are helpful but unless seen flying solo or in pairs along canyon walls (ravens) or as a "murder" (crows) I frequently find it difficult to decide what I'm looking at. Although we are shown as being on the edge of their range, American crows are often seen here in large numbers.

I’m still having trouble with ravens and crows.  If I see a small flock - say 5 -  does that mean it can’t be a raven?
