Wildlife photography of an American Bison Bull in early morning fog in Yellowstone National Park’s Hayden Valley

Early morning fog bestows an almost painterly quality on this image of a lone bull American Bison meeting the new day in Yellowstone National Park’s Haden Valley. This bull is still shedding his winter coat, which they rub off against trees and boulders as it begins to itch in the Spring. As summer sets in, Bison also start to wallow in dry bowls of dust or sand, protecting them from biting insects.
