Animals Behaving Badly-- Untamed animals will walk among us. They are in our cars, our yards, our homes, and in our face. They want what we want: territory and shelter, food and water. Some ingenious, scrappy and resilient creatures have found ways to challenge and exploit us. Outrageous, funny, but also thought provoking, this episode of NATURE explores the ever-escalating battle for space between animals and humans. What hand do we have in their actions? Who's in charge when animals and humans collide?-- The Good, The Bad, and The Grizzly-- Once threatened with extinction, the grizzly bear is back. The abundance of 'the biggest, baddest carnivores in the lower 48' may rank as the biggest success story in conservation history. But success always comes at a price - and someone has to pay. In this compelling episode of NATURE, America's greatest predator struggles to survive on a modern frontier. Meet the homeowners who find themselves under siege from foraging grizzlies, the ranchers whose livestock is at peril, and wildlife managers charged with keeping the peace between bears and humans. In the words of one observer, 'We're still scared of them, but they're not scared of us.'
