Pronghorn antelope, pronghorn sheep, American antelope or prongbuck, all of these names refer to the same species native to North America which is simply called Pronghorn. Although this hoofed species looks like an antelope or a goat, it’s unique enough to have its own taxonomic family, Antilocapridae. Same with its relatives, all pronghorns have a pair of horns. While the female’s horns are usually just little more than bumps, the male’s horns can reach 12 inches long. The shape of these horns are also distinctive, they point backwards and branch as its name implies.  The pronghorn isn’t born with the horns or carries them all life long. Every year after the mating season, the horns would shed and regrow during the winter. Before spring, all males will have their horns ready to compete for territories. The pronghorn is not a large animal, it is usually between 2.5 to 3 feet at shoulder height. Regardless of sex, pronghorn have reddish-brown fur and striking white markings that adorn their face, neck, and stomach.. The white hairs on its rump are longer and can become visible when stuck up.
