Pronghorn antelope prefer to feed on grass, sagebrush and other vegetation found in the foothills of the mountains where they live. They may also feed on cacti. Like cattle, pronghorns regurgitate partially digested food known as cud, chew it and swallow it again.
Pronghorn antelope live in the foothills of the Rocky Mountains in the United States and Canada. They are one of the fastest land-dwelling species on the continent, reaching speeds of up to 53 miles per hour. This allows them to escape from predators, such as coyotes and big cats. They develop this running ability early on; young pronghorns are capable of successfully fleeing from humans within a few days of their birth.
The average pronghorn antelope weighs between 90 and 150 pounds and is about 3 feet tall at the shoulder. Pronghorns have brown coats with white patches on their stomachs and white stripes on their throats. They also have large, curled horns that can extend more than a foot long. During the winter months, they travel in large herds, but in the spring, they divide into smaller groups. The adolescent males typically band together, adult males live alone, and females form small groups. In the fall, the males approach the groups of females to mate.
