That's a pretty cool picture. I've never seen a bird do that before! Must have been really cold that day...

But did you know that crows also count? They keep a close eye on hunters, knowing the difference between a hunter with a gun and a farmer with a rake. If three hunters enter a blind and only two emerge the crows will keep their distance, knowing full well that one still lurks inside. They are not fooled until the number of hunters reaches five, with only four leaving the blind. The crows may then feel confident enough to return to the area, having lost track of the remaining hunter still waiting for them.
