The bison is the largest land mammal in North America. In a typical year, more than 3,000 bison roam the grasslands of Yellowstone National Park. Bulls are more massive in appearance and for their size, bison are agile and quick, capable of speeds in excess of 30 mph. Each year, bison injure park visitors who approach too closely.
