I'm with starrmans uncle. I've had trouble with crows for about three years now. Its legal to hunt them in ny on fri. sat. sun. mon. I believe they do warn the other animals in the woods of danger. They may be just making the noise to warn there own but if the other animals hear it they probably know to stay away. they are a smart bird. I've also noticed if they're next to me making alot of noise I won't see deer that day.
