The scarlet ibis, sometimes called red ibis, is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.
Region
Tropical South America and Caribbean
Typical Environment
Found along the northern coast of South America from Colombia and Venezuela through the Guianas to northern Brazil, and on islands such as Trinidad and Tobago. It favors coastal mangroves, estuaries, tidal mudflats, coastal lagoons, and river deltas, but also uses inland floodplains and rice fields. Breeding colonies are typically in mangrove trees over brackish water, offering protection from predators. Outside the breeding season it ranges widely across shallow wetlands and intertidal flats in search of food.

Its vivid scarlet color comes from carotenoid pigments in crustaceans; birds kept on low-carotenoid diets fade to paler orange. It nests colonially in mangroves and is the national bird of Trinidad and Tobago. Flocks often fly in lines or V-formations between feeding and roosting sites.

"While showering dignity and color on the scarlet ibis, nature seems to have been reluctant in the bestowal of weapons. The bird's beak was blunt, its toenails were unsharpened, and its eyes had a gentle, soft Bambi quality." – Dr. Paul A. Zahl, Coro-Coro [30]
Temperament
social and active
Flight Pattern
steady wingbeats with occasional glides; often flies in V or line formations
Social Behavior
Highly gregarious, forming large flocks for feeding, roosting, and nesting. Breeds colonially, often with other herons and ibises, building stick platforms in mangroves. Pairs are seasonally monogamous, and both sexes share incubation and chick-rearing duties.
Migratory Pattern
Partial migrant
Song Description
Generally quiet, vocalizing mostly at colonies and in flight. Calls are harsh grunts and nasal honks, often given in series during social interactions.
