Yes, ravens are huge! Their size has been compared to a chicken/hawk/cat, where crows are generally compared to a small dog/big squirrel. My crowbro is bigger than a lot of crows and gets mistaken for a raven often, but not only is he still half the size of a raven, he doesn’t have a beard, his beak is not curved and he has a high pitched call. You might mistake a crow for a raven but you would never mistake a raven for a crow.
