The Living Edens Episodes on PBS

Naturalist Paul Schullery follows wildlife over the course of a year in “Yellowstone: America's Sacred Wilderness.” The stars of Schullery's show: wolves, whose reintroduction in 1995 helped restore the park's ecological balance (as did the return of mountain lions). But that's bad news for elk and coyotes. Meanwhile, grizzlies have their own agendas: taking care of their cute and curious cubs. And the ospreys? They go fishing.
