All bears have 5 toes, with the front foot short and about 4-5 inches wide. The hind foot is long and narrow, measuring about 7 inches. Claw marks may or may not be visible. Bears use trails just as people do since it's easier to travel on a trail than through underbrush. It's easy to recognize a black bear's sizable droppings of plant leaves, partly digested berries, seeds or animal hair.
Black bears are solitary.
They don't associate with other bears except sows with cubs or during breeding. Bears are intelligent and curious. They can see colors, form and movement. Although their vision is good, they generally rely on their acute senses of smell and hearing to locate food and warn them of danger. Adult black bears make a variety of sounds.
