Are Crows And Ravens The Same?

They are members of the same genus. In this instance, crows and ravens are both proud members of the Corvus genus, but they aren’t members of the same species. As members of the same genus, crows and ravens (and rooks, the third member of the Corvus genus) share very similar attributes or characteristics.

Apart from pigeons, crows might be one of the most successful birds alive today. Success, though, brings another problem—fame and recognition. Most of us would look at the photo below and identify it as a crow.

Most of us would also be surprised to know that we are wrong. The bird in the picture is actually a raven.

What’s the difference between a crow and a raven? Let’s find out!

Crow Vs. Raven

Crows and ravens suffer from the same problem that pigeons and doves face—a classic case of mistaken identity.

They are members of the same genus. Crows and ravens are both proud members of the Corvus genus, but they aren’t members of the same species. As members of the same genus, crows and ravens (and rooks, the third member of the Corvus genus) share very similar attributes or characteristics. This also means that they’re placed very close to each other on the phylogenetic tree. Even so, crows and ravens are decidedly not the same bird.

The crow versus raven debate rages on quite intensely in North America. Much of this simply comes down to the fact that ravens and crows are the only two birds decked out in all black (from beak to tail) across the whole continent.

How Similar Are Crows And Ravens?

As mentioned before, crows and ravens are completely black. They both also possess shiny plumage. If you were to come across either bird on a sunny day, their bodies would glimmer in the sunlight.

They’re both also incredibly intelligent animals. A study in 2014 aimed to determine exactly how smart corvids (members of the larger Corvidae family) really are. Researchers at the UC Santa Barbara, USA and University of Auckland, New Zealand worked with New Caledonian crows. They found that these corvids could perform tasks nearly as well as seven- to ten-year-old human children. In essence, with just around five months of training, New Caledonian crows were able to perform alien tasks (based on water displacement) as well as, or sometimes even better than first graders.

Similarly, in Germany, at the Osnabrück University, researchers used a broad array of tasks to measure the intelligence of young ravens. According to Simone Pika, lead author of the study, young ravens were found to possess an incredible quantity of intelligence for their age. In her own words, Pika had the following to say to Scientific American about raven intelligence, “We now have very strong evidence to say that, at least in the tasks we used, ravens are very similar to great apes.”

Members of the Corvus genus have also been well-documented in their use of tools. They’ve been observed using tools like sticks or branches to reach into logs to pick out small bugs.

In fact, this documentation of corvid intelligence and tool use began as early as 620 B.C.E. when an ancient Greek storyteller, Aesop, observed a crow drop rocks into a vessel containing water. The bird did this to raise the level of water in the vessel.

So, How Can We Tell The Two Apart?

Ravens are larger than crows. Crows come in at about 17 inches in length, while ravens are around 27 inches. Ravens are almost comparable to a few species of hawks in terms of size. They’re notably longer in length and have a greater wingspan than crows.

Another easy to way to tell them apart is based on their shimmer in the sun. Crows shimmer with a greenish tint when flying high in the sky, while Ravens have more of a blue or purple tint.

Although we can find both birds in cities and in the wild, each has its own quirky habitat preferences. Crows like living around human civilizations and are more social and outgoing in terms of their personalities. On the contrary, ravens prefer open spaces and can be more commonly found in wilder areas.

Surprisingly, one of the easiest ways to tell crows apart from ravens is not a visual cue at all. Instead, it’s auditory. Crows make a very distinct “caw-caw” call. It’s very hard to miss, mainly because it’s one of the first sounds we ever learn about (dogs bark, cows moo, crows caw, and so on). It’s always very high-pitched and screechy in nature. Ravens, on the other hand, are more hoarse. They don’t screech at all, but rather croak (yes, like frogs). They make a very characteristic and low-pitched “gronk-gronk” call.

Conclusion

Crows and ravens are two incredible, yet very different kinds of birds. So, next time you spot a black bird flying about in the sky, don’t automatically assume it’s a crow. Use a bit of that mighty human intelligence and give these corvids the respect they deserve by identifying them correctly!
