Pronghorn in Snow, Yellowstone National Park, WyomingIt was a spring snowstorm when I photographed this pronghorn in Yellowstone National Park. Likely just chewing on some grass, but I like to think that he was trying to catch snowflakes with his tongue. Nikon D300 with Nikkor 200-400mm lens (at 310mm) ISO 800, f/5.6 at 1/1000th of a second.
