Nature Extraordinary Animals - Bears and Wolves Two-Disc

Program 1: Encounters of Bears and Wolves - 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. Program 2: White Falcon, White Wolf - On Canada's remote Ellesmere Island, where June is spring, July is summer and August is already Autumn, the race is on for two remarkable species to raise their families. The white gyrfalcon is enormous, the largest and most powerful falcon in the world. Yet last summer, the nesting falcon pair here failed to raise any young. The rare Arctic wolves rely on every member of the pack to chase and bring down the prey that keeps them alive. Last year was good to them, and they raised three cubs. But for the wolves and the falcons, as well as for the snowy owls, musk oxen, lemmings, Arctic foxes and hares who share this fragile ecosystem with them, fortunes are always precarious.
