Fundamental to the survival of the grizzly bears of Yellowstone National Park is a sufficient supply of its four key natural foods: meat, cutthroat trout, moths, and whitebark pine. Not only do these foods provide the grizzlies with nutrients vital t...o their diet, but the location of the food helps to keep grizzlies safe from humans. Due to various factors, the supply of each of the four foods is either gravely threatened or faces an uncertain future. This video from Nature examines these four foods as they relate to the survival of the grizzlies of Yellowstone. Closed captioning included. Run time 03:54.
