This nature compilation brings together four documentary series narrated by British naturalist Sir David Attenborough. PLANET EARTH describes the interrelation between wild animals and their often unforgiving habitats. It features episodes such as "Deserts," which takes a close look at the arid terrains of the Sahara and the Sonoran; and "Ice Worlds," which focuses on the Arctic region and Antarctica. The 10 chapters of THE LIFE OF MAMMALS chronicle the evolution of this group of warm-blooded vertebrates, while THE BLUE PLANET features eight episodes exploring marine life and biology: "The Blue Planet," "The Deep," "Open Ocean," "Frozen Seas," "Seasonal Seas," "Coral Seas," "Tidal Seas," and "Coasts." the BBC NATURAL HISTORY COLLECTION also includes 10 episodes from THE LIFE OF BIRDS, which examines the behavioral patterns of various vertebrates, among them, the sand grouse, the snowy owl, the African Harrier Hawk, and the ostrich.
