Crows and other birds are that smart. As I would snipe starlings the crows and songbirds would perch nearby to watch the show. The songbirds would actually land withing 6 feet of me. The crows would fly where the dead starling were still in the tree, flick them into the air to to ground. Then fly back to the perch and caw waiting for me to kill another. Starlings are truly the universally hated bastardss of the bird world.Crows are smart. Probably smart enough to figure out you shoot starlings but not crows. If you shoot a crow and leave it on the ground crows are likely to stay away for a year or two. They will also remember you're the evil guy who shoots crows, and give alarm calls when they see you. Young crows will learn you are an evil grow killer from other crows even if they never saw you kill a crow or saw any dead crows. Interesting university study showed the crows recognized individual human faces too, so can distinguish evil grow killing humans from other humans.
