The American pronghorn is the only living species of the Antilocapridae family, all other members are extinct. The pronghorn is a small ruminant mammal which bears small forked horn and which resembles an antelope.

The horns resemble other bovids in that they have a horny sheath but the horns are shed outside the breeding season and subsequently regrown.

The pronghorn is the sole extant member of the family antilocapridae. The pronghorn is indigenous to interior western and central North America.

Though not an antelope, it is often known colloquially in North America as the American antelope, prong buck, pronghorn antelope, or simply antelope because it closely resembles the true antelopes of the Old World and fills a similar ecological niche on this continent.

While driving through the Great Divide Basin, I saw many pronghorn, some even close to the road making good photos possible. Most times, these animals are reclusive and stay far from any contact with humans.

This buck was about one hundred feet from the highway when I slowed to a stop. He started to walk off but I called out with my squeal and he stopped and looked my way. That is when I took the first photo. He did not stand there very long but turned and began walking away, which is when I took the second photo above.

As the buck was walking away, something else, a movement caught my attention. I pointed my camera toward the place where I saw the movement and when the focus came in, I snapped this photo.

Later, I see a couple more females grazing on the grass.
