A species achieves Least Concern status when there is a low risk of being threatened. Hemker Park & Zoo holds the following Least Concern species.
The pronghorn is the only surviving member of the family Antilocapridae.
Though not an antelope, it is often known in North America as the prong buck, pronghorn antelope, or simply antelope because it closely resembles the true antelopes of the Old World.
Pronghorns form mixed-sex herds in the winter. In early spring, the herds break up, with young males forming bachelor groups, females forming their groups, and adult males living solitarily. Some female bands share the same summer range, and bachelor male bands form between spring and fall.
