Pronghorn: Lamar Valley, Yellowstone National Park, September 2024 — We used to call these Pronghorn Antelope, but they never were part of the Antelope family. Pronghorn have a family all their own, and while distantly related to the antelopes of Africa and Asia, and goats and deer world-wide, their closest relatives are the giraffes and okapi of central, east, and south Africa. What I found most interesting in watching this small herd is the way the bucks “herd” the does and fawns exactly as a sheep dog herds sheep, from behind mostly, working the edges to keep them bunched and moving, and aggressively running down any that would stray. Fun to watch. Sony a6700 with Tamron 50-400 Di iii zoom at 600mm and 423mm equivalent. Program mode with my bird and wildlife modifications. Processed in Photomator.
