Buffalo

The American Bison (American Buffalo) is a bovine mammal, the largest terrestrial mammal in North America, and one of the largest wild cattle in the world. With their huge bulk, Wood Bison–which are the largest subspecies in North America – are only surpassed in size by the massive Asian gaur and wild water buffalo. The bison inhabited the Great Plains of the United States and Canada in massive herds, ranging from the Great Slave Lake in Canada's far north to Mexico in the south, and from eastern Oregon almost to the Atlantic Ocean, taking its subspecies into account. Its two subspecies are the Plains Bison, distinguished by its smaller size and more rounded hump, and the Wood Bison, distinguished by its larger size and taller square hump.
