Two American Bison (Bison bison) charge one another in a rivalry for superiority. Captured at Yellowstone National Park in June 2013. Bison stand 72 inches or more at the shoulder and can weigh up to 2200 pounds (over one ton). When the need arises, they can run up to speeds of 40 miles per hour--an incredible feat for such a large animal!
