Pronghorns are found throughout western and central North America. Although, they resemble Old World antelopes, they are not of the antelope species. They are their own separate species and are deer-like in appearance and have hooves. Pronghorns are also known as American Antelope, Prongbuck, Pronghorn Antelope, or Prairie Antelope. The males have horns that are 5-20 inches (13-51 cm) long, each with a prong. The females have small horns ranging from 1-6 inches (2.5-15 cm). I found these two with a group of Pronghorns in a Pinyon-Juniper forest area, close to the Grand Canyon.
