3. I live in Laguna Beach, CA. I feed both the Crows and Ravens. I noticed the beak difference, definitely the size and the sound they make. I especially watch one big raven, guessing male...named him “big poppy”. He’s 3 times the size of any crow in the murder I feed. I noticed that the crows and ravens don’t really interact. The murder I feed is approximately 15-20 birds. There are two crows that actually mimic human sound. One clearly says “hello, hello” and we’ve had short conversations, the other makes a few different noises, not quite sure what he’s mimicking, but “hello” comes out at the end.
