Nature's Great Events - Season 1 Episode 2
Every year, the survival of grizzly bears in North America depends on a spectacular natural event: the return of hundreds of millions of salmon from the Pacific Ocean to the mountain streams where they were born. This great return provides food not only for bears, but for killer whales, wolves, bald eagles and the very forest itself. Will the salmon return in time to keep the hungry bears alive?
