Nature (1982)

Season 28: Episode 6

The wilds of Yellowstone National Park are a world of predators, scavengers and opportunists. In this vast and complex kingdom, two dominant predators reign supreme: the grizzly bear and the wolf. Size and power square off against speed and teamwork, as mighty grizzly bears contend with powerful packs of wolves for control of the food supply. Though these two fearsome hunters would normally rule their ranges uncontested, in Yellowstone they must share resources, or face starvation.
