I live in a town of about 700 or less. On occasion I have witnessed crows take walnuts off of the Walnut Trees here in Isleton.....they fly up with them and then drop them on the cement or street....they fly down and check to see if the meat is exposed....if not, they pick up the walnut and keep repeating the dance until they get the meat out....At first I thought that this was funny, but now I realize that they are extremely intelligent creatures. When they sit in trees and caw to me, I know they have a message for me and I just have to listen to my intuition and know what they are trying to tell me....
