Bison Rut

Some of the bison herds of Yellowstone National Park make their way to Hayden Valley, between Lake and Canyon Village, to strut their stuff during the annual rut. This valley will witness 2,000 pound animals squaring off in an all out battle to win the courting rights to the females. Taken with Nikon D200.
