O. cervina Desmarest The bighorn sheep (Ovis canadensis) is a
species of sheep. They live in North America. Their name was
given to them because of their large horns. Their horns can
weigh up to 30 pounds (14 kg). However, the sheep themselves
weigh up to 300 pounds (140 kg). In a genetic testing, it was
found that there are three subspecies of bighorn sheep, one of
which, is endangered (Ovis canadensis sierrae). The bighorn
sheep came from Siberia. They crossed to North America over the
Bering land bridge. The population grew in the millions. It then
became one of many mythologies of the Native Americans. By 1900,
the population got smaller to several thousands. Many
organizations, including the Boy Scouts of America, has helped
increased the population. - Allen, J. A. 1912 "Historical and
