A small group of Bison foraged in the sagebrush off one of the roads in the Lamar Valley of Yellowstone National Park in late October. A few inches of snow covered the ground making the grasses they eat a bit more difficult to access. This young calf made the most of it as evidenced by the snow and icicles dripping from its chin. It seemed very curious about us and looked directly into my lens. Nikon D5, Nikkor 500mm PF.
