Some bears may bluff charge to within a few feet. If this occurs, stand your ground, wave your arms wildly, and shout at the bear. Turning and running could elicit a chase and you cannot outrun a bear. If a bear attacks, fight back as you continue to leave the area. Bears have been driven away with rocks, sticks, binoculars, car keys, or even bare hands.
Black bears are intelligent and curious.
Although their vision might not be as good as a human's, studies show bears can see colors, recognize human forms, and particularly notice movement. Bears usually rely on their acute sense of smell and, to a lesser degree, hearing to locate food and warn them of danger. Bears are heavy and have short, powerful legs. Adults usually weigh from 200 to 600 pounds, with rare individuals weighing up to 900 pounds. An adult male normally weighs more than an adult sow, sometimes twice as much.
