The hidden world of the harpie eagle is explored in Venezuela's Orinoco River jungle, where a nest-cam is placed in the home of a family of the big birds, which can stand 3-ft. tall and possess 6-ft. wingspans. While the mother stays in the nest to protect its chick, the father heads off in search of food, returning with such delicacies as howler monkeys, capuchins, and sloths.
