Despite their hefty size, bison are quick on their feet. When the need arises, they can run at a speed of up to 40 miles an hour.
Their curved, sharp horns can grow up to 2 feet long. Their horns may break when they dig mud; once it breaks off, it won’t grow back.
The American Bison spends the warm hours of the day resting, chewing its cud, or wallowing in the dirt.
