The Andean flamingo (Phoenicoparrus andinus) possesses the typical elegant flamingo body shape, with long legs and a long, curved neck. The body is pale pink, with bright upperparts and a noticeable patch of black on the wing. The legs are yellow and the large, curved bill is yellow and black. Young birds are grey in colour before they develop the pink adult plumage. Andean flamingos feed entirely on tiny algae called diatoms. Flamingos are long-lived birds, reaching up to 50 years old.
