the most popular crazy sheep of Rocky alongside North American mountains; the bighorn, Oris montana.
a minimum of six species and two subspecies of Ovis have been described from North America, however it is possible any particular one or two of the may well not stand the test of further analysis. The northernmost species is the white or Dall's sheep, O. dalli, widely spread over north Alaska. The southernmost and smallest is O. mexicana, from northern Mexico therefore the adjoining areas of brand new Mexico. The black colored or Stone's sheep, O. stonei, from Alaska and British Columbia, is extremely dark with white stomach and markings down the legs. Other species tend to be O. nelsoni and O. fannini.
