The term 'Rockies Grazers' refers to two animals that inhabit the Rocky Mountains in North America. The first is the elk, or Cervus canadensis, which is a species of deer that is native to the region and is also known as the wapiti. The second is the mountain sheep, or Ovis canadensis, which is a species of wild sheep that lives in the high elevations of the Rocky Mountains. Both of these animals are grazers, meaning they feed on grasses and other vegetation.
