Mountain Sheep (C/N)

The bighorn sheep (Ovis canadensis), also known as the mountain sheep, is one of three species of mountain sheep that primarily live in North America and Siberia. They are named for their large, curved horns borne by the males (known as rams), which are smaller in females (known as ewes). The horns can weigh in excess of thirty pounds, whereas the average adult weighs around three hundred pounds. By the year 1900, the population of these animals had declined to several thousand, due to diseases, although conservation efforts have managed to restore the population.

In The Lost World, mating behaviors in mountain sheep is one of the subjects that Richard Levine sends Arby and Kelly to Xerox papers on at various Stanford libraries.
