The pronghorn live in the open prairies and sagebrush plains. Grasses seem to be the least of these in which they eat. The Pronghorn have horns and not antlers. They are the only horned animal to shed their headgear each year. They actually only shed the sheath, the outer covering of their horns.
Pronghorns also have very good eyesight.
They can see small moving objects up to four miles away.
