Natural World: Big Sky Bears

Documentary about Montana's Rocky Mountain black bears. A mother has just given birth to two tiny cubs. The forest looks an idyllic playground but it will take all mother's skill, and plenty of luck, if the twins are to survive the summer and learn to fend for themselves. She teaches them how to find food by raiding ants nests, picking berries and catching trout, but her greatest challenge is avoiding the wolves, coyotes and grizzlies. To keep them alive, she must teach them to climb trees.
