American Bison are the largest land mammals in North America. They stand some 5 to 6.5 feet tall at the shoulder and weigh between 1000 – 2000 pounds. Despite their massive size, bison are quick on their feet. When the need arises, they can run at speeds up to 40 miles an hour and jump up to 6 feet vertically. The hump between their shoulders is made of muscle and helps them push through deep snow. Bison are ruminants, which means they have a multichambered stomach that allows them to digest grass and other plant matter. This suits them well as they are grazers that primarily feed on grasses.
