Late summer (August-October) males establish harems.
May-June at 5 days fawns are usually able to out run a person.

Both sexes have permanent horns with sheath. Male horn usually longer than ears, females are shorter. Both lose outer sheath. Females have no black patch on cheek. Pronghorn are gregarious and can run 60 mph, making it the fastest land animal in North America. They have keen vision, good sense of smell, and excellent hearing. They sometimes display a three step warning by first pawing the ground, then urinating in that spot, and finally defecating in that spot.
