The scarlet ibis is a striking tropical bird that is completely red except for its black wingtips. Its colouring, which intensifies as the bird ages, is the result of a diet heavy on crustaceans, which it plucks from mud and water with its long, curved bill. The scarlet ibis is a social bird, living in large flocks in the same general area for most of its life. Males attract their mates with a number of displays, including songs and dances.
