A nature documentary about a bird's-eye view of the natural world, joining the journeys of snow geese, cranes, albatrosses, eagles and other birds across six continents. Beginning in North America, snow geese face their biggest predator, pelicans glide under San Francisco's Golden Gate Bridge, bald eagles in Alaska swoop among brown bears, and on the Great Plains, cowbirds dive under the feet of fighting bison.—Joyce M
