Bighorn sheep (Ovis canadensis) is a species of sheep in North America with large horns. The horns can weigh up to 30 pounds (14 kg), while the sheep themselves weigh up to 300 pounds (140 kg). Recent genetic testing indicates that there are three distinct subspecies of Ovis canadensis, one of which is endangered: Ovis canadensis sierrae.

Ovis canadensis is one of three species of mountain sheep in North America and Siberia; the other two species being Ovis dalli, that includes Dall Sheep and Stone's Sheep, and the Siberian Snow sheep Ovis nivicola.
The taxononomy of Ovis canadensis continues to be modified as new genetic and morphologic...
