Grizzly in Snow, Yellowstone National Park, WyomingThere are three different species of bear in the United States — the black, brown and polar bear. The term grizzly bear refers to the subspecies of the brown bear that ranges from Alaska down into Wyoming, also known as the North American brown bear. I photographed this one playing in the snow in Yellowstone. At least it looked like he was playing in the snow as he sat back, grabbed his feet and rocked back and forth. Nikon D300 with Nikkor 200-400mm lens (at 550mm with 1.4 TC) ISO 800, f/5.6 at 1/5000th of a second.
