Marabou storks are one of the largest flying birds in the world—their wingspan can reach ten feet! Like other scavengers such as the vulture, they’ll eat just about anything, whether alive or not. They like to pick through lions’ and tigers’ leftovers. Their cleaver-like beaks help them cut through even the toughest meat. The feathers on their bodies and wings are dark gray, but their heads and necks are bald; the skin is pink and turns bright blue-green during breeding season. Marabou storks nest in colonies of up to sixty pairs. Females lay one to two eggs, and both parents share the job of sitting on the eggs in the nest. Babies feed on food their parents regurgitate onto the nest floor. Marabou storks have no voice box; they thus communicate with each other by clacking their beaks together. Their throat pouch contains red or pink air sacs that the bird can inflate and deflate—this may play a role in courtship. Marabou storks can live up to twenty-five years.
