I can't believe that much about a bird, called a crow, could guide you from all incoming dangers. Think about it, you are walking with your dog in a remote area away from your home and sometimes your dog leads you and you happen to be a follower. You are concentrating on your dog not your path (position) where you are. And you are lost in the wilderness. You are desperate and very sensitive to any possible suggestion.
Imagine that a crow is flying towards you, crying, that means there is a danger where it is flying from and it is letting you know to avoid it. What would you do?
If I were in those shoes, I would take that crow's message and walk towards the danger, because it's danger is obviously human and I could get my direction from there !! It works, doesn't it?
