The Coyotes in Yellowstone National Park were ubiquitous last month when we were there. We saw and photographed them at least once each day and often it was with prey in their jaws. Late one afternoon we watched this Coyote trotting by clenching something in his teeth. Our driver shouted that it was a duck. Of course when we viewed our photographs that evening, it was obvious that the Coyote had a hoof in its mouth. It had come across a bison carcass, possibly a wolf kill. The Coyote seemed pretty pleased that it had made off with the foreleg of the unfortunate critter. We searched for it the next couple of days but never found the hidden carcass.
