The gaur, also known as the Indian bison, is a bovine native to South Asia and Southeast Asia. The gaur has been recognized by wild life experts as the largest of all wild cattle, bigger even than Asian wild Water Buffalo and American Bison. A gaur herd includes females and one dominant male. Bulls often congregate into bachelor herds while older males occasionally prefer living solitarily.
