Bison are members of the genus Bison of the Bovid family of the even-toed ungulates, or hoofed mammals. There are three types of living bison:

  • The American bison (Bison bison bison), the most famous bison, formerly one of the most common large animals in North America
  • The Wood bison (Bison bison athabascae), considered to be a subspecies of the American bison
  • The European bison or Wisent (Bison bonasus)

There were also several other species of bison which became extinct within the last 10,000 years.

Bison are very closely related to cattle, yaks, true buffalo, and other members of the subfamily Bovinae, or bovines.

Bison physiology and behavior

Bison are among the largest of hoofed mammals, standing 1.5 to 2 meters (5 to 6.5 feet) at the shoulder and weighing 350 to 1000 kg (800 to 2,200 lbs). Males average larger than females. The head and forequarters are especially massive with a large hump on the shoulders. Both sexes have horns with the male's being somewhat larger. (Nowak 1983).

Bison mature in about two years and have an average life span of about twenty years. A female bison can have a calf every year with mating taking place in summer and birth is spring when conditions are best for the young animal. Male bison fight with each other over the right to mate with females.

The bison's place in nature

Bison are strictly herbavores. American bison, which live mainly in grassslands, are grazers while European bison, living mainly in forests, are browsers.

The American Bison was depicted on the reverse side of the U.S. "buffalo nickel" from 1913 to 1938. In 2005, the United States Mint coined a nickel with a new depiction of the bison as part of its "Westward Journey" series; the Kansas and North Dakota quarters have a depiction of the bison on its reverse as part of its "50 State Quarter" series. The Kansas State Quarter only has the bison and does not feature any writing. The North Dakota State Quarter has two bison.


The bison is a symbol of Manitoba, the Royal Canadian Mounted Police, Bucknell University, the University of Colorado, Lipscomb University, Harding University, Marshall University, the Independence Party of Minnesota, and North Dakota State University. It is also commonly used as a symbol of the city of Buffalo, New York and its professional sports teams, the Buffalo Bills and Buffalo Sabres, although the city was not named for the animal. The bison is also the state mammal of Wyoming. It is the state animal of Kansas (see Governor of Kansas Quick Facts).
