Dumbest animals have to be any male in the rut, they know better but refuse to act smart. Second dumbest is one particular whitetail doe I ran across 2 years ago. It was all alone and obviously its first winter based on the size. I was hunting over a green wheat field that we knew coyotes had run everything off of. We set up a coyote call and then proceeded to wait for deer, with the thought that if it turned dark we could flip on the coyote call and see what would come in. The doe came in half an hour before last light, and we decided to not shoot as it was too small to fill a freezer. After hunting light was over we hit the coyote call, rabbit in distress, and the doe went over and sniffed it, then returned to browsing just a few feet from the call. When we gave up on coyotes she was still there, we climbed down from the stand and she came over to within 10 yards of us. She then waited as we walked away before returning to the wheat. I feel fairly confident she didn't live out the year. So this brings up the philosophical question, which is dumber the one who knows what to do and doesn't do it, or the one who doesn't know what to do?
