Black bears are not well suited for the type of hunting that wolves and mountain lions do. While they can run fast for short distances, they are flat footed and so don't do so well in long distances. Neither are they socially cooperative in the way that wolves are. Only about fifteen percent of black bear's diet is comprised of animal protein, and much of the animal matter that they consume is in the form of insects. Apart from the food scraps that this black bear undoubtedly finds in my compost materials, the compost pile attracts insects that the bear may eat.
