McGowan of the Cornell Lab of Ornithology writes on his crow FAQ page, ravens soar longer than crows, and you can see through their wing feathers as they fly (among other differences). And the birds' calls are substantially different. "American crows make the familiar caw-caw, but also have a large repertoire of rattles, clicks, and even clear bell-like notes," McGowan writes, whereas common ravens have "a deep, reverberating croaking or gronk-gronk. Only occasionally will a raven make a call similar to a crow's caw, but even then it is so deep as to be fairly easily distinguished from a real crow."

Do crows have feathers?
Feathers do not last forever , and after a year of hard service, the crows’ feathers begin to lose their glossy blue-black patina and become dull, with muted shades of sepia and grey. Luckily they have the ability to grow a new set of spanking new ones, but this metamorphosis comes at a cost. The process takes a lot of energy, which is why it’s usually timed for a period of relatively low corvid activity — after nesting and before migration (for those who head to warmer climes for winter). They need rest and good nutrition to grow the new feather cloak and hormonal changes associated with the process can make them feel out of sorts.
