A young Pronghorn buck is just developing the prong on his horns. Those small tips will eventually grown into the pronged pair of horns that gives this ungulate its name. He is alert to his surroundings, ears sensing something and those huge eyes watching for danger. We were shooting from the side of the road, inside our van, with it serving as a blind for us. A lone photographer approached the small band of Pronghorns outside on foot, walking too quickly without regard for them and causing a disruption in their tranquil feeding. Upset by his presence, they bounded away across the meadow and disappeared, demonstrating their prowess as the fastest land animal in North America.
