Bison Hunt

Hundreds of bison have left the boundaries of Yellowstone National Park this winter in search of food. The annual hunt for wild bison migrating from Yellowstone National Park has hit its highest level in decades. Driven by strong participation from American Indian tribes, roughly 250 of the animals have been killed this season after leaving Yellowstone for winter range at lower elevations in Montana.(AP Photo/Ted S.
