Ravens are way larger than crows with a four-foot wingspan and a 25 inch height, while a crow's height is about 18 inches. Ravens also differ in tail and feather shape. A notable difference is the manner in which each bird flies. Ravens can be seen soaring and gliding in the sky and showing off aerial acrobatics while crows will never be seen doing dives and somersault in the air, but ravens love to do it.
