Crows and ravens are both large, black birds that can be found throughout the world. The most significant difference between the two is their size: ravens are much larger than crows. Ravens can reach up to 24 inches in length, while crows are typically around 17 inches. In addition, ravens have fluffier feathers and a larger, more curved beak than crows.
Ravens are also more vocal and have a greater variety of calls than crows. They are also much more intelligent and can even be taught to mimic human speech. Ravens are also more solitary than crows, and prefer to hunt alone. Crows, on the other hand, are more social and tend to hunt in groups.
