Pronghorn: Lamar Valley, Yellowstone National Park, October 2024 — The Pronghorn is the fastest land animal in the Americas and is only outpaced by the Cheetah on the African plains…and that only by a single mile per hour, and, over a short distance. The Pronghorn can run faster and longer than any other land creature. They are built for speed. This shot was just an amble by Pronghorn standards. Sony a6700 with Tamron 50-400 Di iii at 600mm.

Pronghorn: Lamar Valley, Yellowstone National Park, October 2024 — Not a rutting behavior specifically, Pronghorn bucks are in the habit of attacking sagebrush plants with their horns…vigorously. They are actually marking the plants with scent from scent glands at the base of the horns, letting other bucks know that they have claimed this territory. It must be pretty powerful scent to stand out over the sent of the brushed sage itself. Sony a6700 with Tamron 50-400 Di iii at 600mm equivalent. Program mode with my bird and wildlife modifications.

Pronghorn: Lamar Valley, Yellowstone National Park, October 2024 — This buck Pronghorn was in the mood for some loving, and was singing his love song and prancing around to please the ladies. Without success as far as we could see, at least while we were watching. They did not seem to pay him any mind, other than to move on when he wanted them to. This is only part of his mating behavior. More to come. 🙂 Sony a6700 with Tamron 50-400 Di iii at 600mm equivalent. Program mode with my bird and wildlife modifications. Processed in Photomator.

Pronghorn: Lamar Valley, Yellowstone National Park, September 2024 — Here you see the buck Pronghorn doing what I talked about yesterday…rounding up a couple of stragglers to keep his herd together, acting very much like a sheep dog. He is happiest when his charges are as close as in the second photo. Sony a6700 with Tamron 50-400 Di iii zoom at 600mm equivalent. Program mode with my bird and wildlife modifications.

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.
