Scarlet ibis - Adults are 56–61 cm long and weigh 650g. They are completely scarlet, except for black wing-tips. They nest in trees, laying two to four eggs. Their diet is fish, frogs, reptiles and crustaceans. A juvenile Scarlet Ibis is grey and white; as it grows the ingestion of red crabs in the tropical swamps gradually produces the characteristic scarlet plumage.
