Ravens and Crows

Physical description is only one of the four components of telling whether this is a raven or a crow. Can you tell what it is by the description in the article?


On our flight east last week, we left the range of the common raven about the Colorado/Kansas state line. The raven is an iconic species throughout much of the west, northern Canada, Alaska and the northern Great Lakes. There is also an isolated population centered around the Appalachian Mountains, but most folks dwelling in the eastern half of the country have probably never seen one.

That isn’t the case with its cousin, the American crow. This bird truly is American, distributed across the USA in every state. East coast and Gulf coast birders have the difficult task of learning to distinguish between the fish crow and the American crow, but they never have to wonder whether or not a large black bird is a raven.

Where ravens and crows co-exist, telling them apart can be a challenge. Side by side, the raven dwarfs the crow, but if they are not together, it gets trickier. As with many species, the trick is to look for four things: physical description, voice, habitat and behavior. Armed with this kind of information, distinguishing the two species isn’t much harder than a couple of laps in the kiddie pool.

Physical Differences—The raven is far larger, about the size of a redtail hawk; a crow is just larger than a magpie. A raven’s wings span about 46 inches while the crow’s wingspan is 36 inches. In flight, crows have rounded tails but ravens have tail feathers that are longer in the center, giving the tail a more pointed or diamond shape. When wings are outstretched, ravens have five “feather fingers” and crows have four. 

The real distinguishing characteristic though, is the bill. If a crow’s bill can be described as a large pointed chisel, a raven’s bill is a jackhammer.

Voice—Ravens and crows are both vocal birds and that really helps in identifying the two. Crows caw. It is a little high-pitched and nasal but distinct enough that you might think they are actually saying the word, “caw”. Ravens, on the other hand, give a lower, coarser croaking sound. I suppose other ravens find it attractive but it is a bit grating to many human ears. In addition, the crow has a rattle call that sounds like a stick against bicycle spokes. The raven’s alternate call is called a knock and sounds like someone tapping on a wooden door—tok, tok, tok. 

Habitat—Crows have adapted to humans and find city life much to their liking. They like trash, city parks and the party life. Ravens prefer less developed areas and open spaces.

Behavior—Crows like company and are often seen in groups. During winter, the groups can be huge. Ravens are a bit more antisocial, usually traveling alone or in pairs. Where crows have adapted well to civilization, ravens are far less trusting and will move off when humans approach.

Ravens also soar much like hawks and on windy days often perform acrobatics such as barrel rolls. Crows rarely soar for more than a few seconds and are not interested in showing off their flying skills.

With these tips, it should be pretty easy to determine whether or not the next large black bird you see is a raven or a crow. Then you can start working on distinguishing the common raven from the Chihuahuan raven and the American crow from the northwestern and fish crows.   

TAX DAY is coming! Here is a chance to do something good with a bit of your tax return and make the day less painful.

Donate part of your tax return to support wildlife in Idaho!

On the second page of the Idaho Individual Tax form 40 you have the opportunity to donate to the “Nongame Wildlife Conservation Fund”.

Check-off this box on your next return or ask your tax preparer to mark the Nongame check-off on your behalf. You can donate any amount you wish, it all helps to support the wildlife you love.

If you are not from Idaho, check with your own state wildlife agency about how you can help. Many states have a similar program.

"WOW. What a phenomenal piece you wrote. You are amazing." Jennifer Jackson

That is embarrassing, but actually a fairly typical response to my nature essays. Since The Best of Nature is created from the very best of 16 years of these nature essays published weekly in the Idaho Falls Post Register (online readership 70,000), it is a fine read. It covers a wide variety of topics including humorous glimpses of nature, philosophy, natural history, and conservation. Readers praise the style, breadth of subject matter and my ability to communicate complex and emotional topics in a relaxed and understandable manner.

Everyone can find something to love in this book. From teenagers to octogenarians, from the coffee shop to the school room, these nature essays are widely read and enjoyed.

Some of the essays here are my personal favorites, others seemed to strike a chord with readers. Most have an important message or lesson that will resonate with you. They are written with a goal to simultaneously entertain and educate about the wonderful workings of nature. Some will make you laugh out loud and others will bring a tear to the eye and warm your heart.
