Range

There are two species of bighorn in Colorado, the Rocky Mountain, which is native, and the desert bighorn, introduced near Colorado National Monument in 1979. Colorado herds are widely scattered throughout the mountains and foothills of the state. In North America, species of bighorn occur from South British Columbia, southwest Alberta, Idaho and Montana to southeast California, Arizona and New Mexico.
