Pronghorn
Antilocapra americanaAlso known as American Antelope, Pronghorn Antelope, Prong Buck, Prairie Antelope
Pronghorns are the fastest land mammals in the Western Hemisphere, capable of sprinting at speeds exceeding 88 kilometers per hour to outrun long-extinct prehistoric predators. Unique among ungulates, they possess true horns with a keratin sheath that branches into a forward-pointing prong and shedding each year after the autumn rut. Their massive eyes provide a 320-degree field of view, allowing them to detect subtle movements miles away across wide-open sagebrush steppes.

- Why interaction risk is low
- Safe to observe from a distance; avoid approaching wild herds, especially during the autumn mating season.
Responsible observation
- Keep Distance: Use binoculars or a long lens, as herds easily spook and flee when approached.
- Drive Cautiously: Watch for animals crossing rural highways, particularly during spring and autumn migrations.
- Look for White Rumps: Spot distant herds when they raise and flare their white tail hair to signal alarm.
