They are a different species, //So how do you tell the difference between buffalo and bison? Bison have large humps at their shoulders and bigger heads than buffalo. They also have beards, as well as thick coats which they shed in the spring and early summer. Another simple way to tell a buffalo from a bison is to look at its horns//
Done that. Chased by a herd of Bison when snowmobiling in Yellowstone. They stink and can run fast!! There has been a case of someone being trampled by buffalo. However seeing them and the other wildlife in Yellowstone was an experience. Wolf and moose but no bear
