The Scarlet Ibis (Eudocimus ruber), occurs in tropical South America and also Trinidad and Tobago. Although there are specimens in North America, they are not native and have been either introduced or escaped birds.
Adults are 22 to 24 inches long and weigh around 23 ounces. They are completely scarlet, except for black wing-tips. A juvenile Scarlet Ibis is gray-white in color. The scarlet plumage is a result of ingestion of red crabs in the tropical swamps of its native habitat.
The Scarlet Ibis is the national bird of Trinidad and is featured on the Trinidad and Tobago coat of arms along with Tobago’s national bird Rufous-vented Chachalaca.
