Bison (Bison bison) There are two subspecies of bison: wood bison (Bison bison athabascae) and plains bison (Bison bison bison). Both subspecies are very similar, although wood bison are a bit larger and darker and have a larger shoulder hump than plains bison. Size: Bulls are almost 7 ft. (2 m) high at the shoulders. Bulls weigh from 1,100 to 1,980 lb. (500 to 900 kg). Mature bulls are about twice the size of cows. Distribution in North America:
