American Bison - Yellowstone National Park
The American Bison (Bison bison) is a North American species of bison, also commonly known as the American Buffalo. "Buffalo" is somewhat of a misnomer for this animal, as it is only distantly related to either of the two "true buffaloes", the Asian Water Buffalo and the African Buffalo. However, "bison" is a Greek word meaning ox-like animal, while "buffalo" originated with the French fur trappers who called these massive beasts boeufs, meaning ox or bullock – so both names, "bison" and "buffalo," have a similar meaning. In reference to this animal, the term "buffalo," which dates to 1635, has a much longer history than the term "bison," which was first recorded in 1774. The American Bison is more closely related to the Wisent or European Bison.
