When it is late winter and they have gone awhile without food they get pretty brave. They come up in our yard looking for food when it is really cold. They will eat cats, dogs or whatever is available. They have been known to drag crying babies off into the woods, because they sound like dying rabbits. The squeek from this guys boot is what called him in that close, it sounds exactly like a mouse squeeker yote hunters use to get them in close. This guy was clearly provoking him to come closer. He lip squeeked to get him to come back when he started to run off and then ran backwards to make his boot squeek. From my view point the yote was just doing what yotes do...look'n for easy meals trying to survive.
