The Living Edens Episodes on PBS

“Ngorongoro: Africa's Cradle of Life” follows the relentless life-and-death struggle animals face in the verdant 12-mile-wide crater in Tanzania's Rift Valley. Among the predators: lions, vultures, a cheetah brother-and-sister hunting team, and a mother serval and her kittens---several of which become prey for the cheetahs. They're also seen eating a gazelle fawn and its mother. And they catch and kill a wildebeest. But they're scared away from their kill by a hyena. Christina Pickles narrates.
