General Information

The American Bison (Bison bison) is a North American species of bison. These bison once inhabited the grasslands of North America in massive herds; their range roughly formed a triangle between the Great Bear Lake in Canada's far northwest, south to the Mexican states of Durango and Nuevo León, and east along the leeward boundary of the Appalachian Mountains. A bison has a shaggy, long, dark brown winter coat, and a lighter weight, lighter brown summer coat. Bison can reach up to 2 meters (6.6 ft) tall, 3 meters (10 ft) long, and weigh 400 kilograms (882 lb) to 1,000 kilograms (2,205 lb). As typical in ungulates, the male bison is slightly larger.
