Unique to North America, the bald eagle is the continent's most recognizable aerial predator, with a shocking white head, electric yellow beak and penetrating eyes. In the 1960s, this symbol of the United States became an emblem of environmental degradation as the pesticide DDT and other human pressures brought it to the brink of extinction. Following their protection as an endangered species, bald eagles have come roaring back. Photographed by Emmy-winning cinematographer Neil Rettig, this film focuses on the drama of the nest. Even in the best of times, it's a surprisingly tough struggle to maintain a one-ton home and raise chicks until they can hunt on their own.
