The Scarlet Ibis (Eudocimus ruber) is a species of ibis that inhabits tropical South America and also Trinidad and Tobago. It is the national bird of Trinidad and is featured on the Trinidad and Tobago coat of arms along with Tobago's national bird, the Rufous-vented Chachalaca. 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.
