Bears emerging from hibernation this spring have found the Yellowstone landscape full of snacks--tasty carcasses of bison and elk who did not survive the long, cold winter.
This bear (I think it's a grizzly although to my inexperienced eyes it's difficult to tell) munched away on what looked like elk remains for about fifteen minutes, then strolled back into the forest. I've been reading James Halfpenny's excellent book, "Yellowstone Bears in the Wild" and I learned the term "hyperphagia," which describes the intense food consumption that bears undertake in the fall prior to hibernation.
