I have seen a couple incidences of deer behavior that seemed beyond their intelligence level, and my son has seen one such incident. First, my son shot a deer with an arrow. The deer he hit, and a couple others with it, ran 50 yards and stopped. The arrow was still in the deer but one end of it was sticking out. One of the others grabbed the arrow with its mouth and pulled it out. (The deer died shortly after that). I saw three deer, probably a doe and her fawns, crossing a very flat picked cornfield. They traveled a grassy waterway which would have kept them as low as possible. What I would not have believed if I had not seen it myself was that they were walking on their knees rather than their hooves. They traveled at least 50 yards that way! I guess that got them about a foot lower, but they had to swing their heads back and forth to keep going so that movement looked really weird. I was sitting on a bluff overlooking the field so had a very good view. I saw a doe and her two fawns in a shallow creek, about 6 inches or a foot deep and about 30 feet wide. The two fawns started chasing each other around the doe which kicked up a lot of water. The doe then clobbered one of them with one of her front hooves and they quit the shenanigans. It was like she was saying they were not in a good place to be making a ruckus and attracting unwanted attention. One time I saw a deer and a coyote out in a picked soybean field about 600 yards away and looked at them with my binoculars. It was too far to shoot with the rifle I had with. The deer pretty much just stood there and but the coyote looked like it wanted to play. It rolled around on the ground and wagged its tail and got down on the ground and crawled toward it. Finally the deer started walking away and the coyote followed it with its tail wagging. The deer was much larger than the coyote and did not appear frightened, but it did not appear to want to play with the coyote. Eventually the coyote gave up and went away.
