Pronghorn Antelope Antilocapra americana This might very well be a member of the Loper Herd mentioned in the book. This is a male, or buck, antelope. You can tell by the tall black horns on his head and the black stripe on his cheek. A female, or doe, antelope might have short horns, but she'll never have the black cheek patch.
Antelope are grazers and browsers, so they eat lots of grass and shrubs.
They favor eating forbs or weedy plant species in the summer but may switch to shrubs such as sagebrush in the winter if forbs become covered with snow. They eat mostly in the early morning and at dusk, and they bed down to rest in mid morning and early afternoon. The antelope is the fastest animal in the Western Hemisphere. They can run about 70 miles per hour for short distances, and can maintain a speed of about 30 miles per hour for 10-15 miles. Antelope can see movement from 4 miles away.
