The grizzly bear, also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly, other morphological forms of brown bear in North America are sometimes identified as grizzly bears. Grizzly bears are large and range in color from very light tan (almost white) to dark brown. They have a dished face, short, rounded ears, and a large shoulder hump. The hump is where a mass of muscles attach to the bear's backbone and give the bear additional strength for digging. Grizzly bears are intelligent, curious, and have excellent memory, particularly regarding where food sources are located. They have good eyesight and excellent senses of hearing and smell. Grizzly bears are active during the day and night, but will often alter their habits to avoid humans in areas of high human use. Predators of Grizzly Bears include humans and cougars.
