American Bison: Lamar Valley, Yellowstone National Park, October 2024 — Now that I am back from Costa Rica, it is time to finish up the photos I took in Yellowstone in October. We were there just in time to see the last Red Dogs of the season…calves born late and still in their reddish-brown coats. Sony a6700 with Tamron 50-400 Di3 at 600mm equivalent. Program mode with my birds and wildlife modifications. Processed in Photomator.
