The toco toucan (Ramphastos toco) is a species of bird in the toucan family Ramphastidae. It is the largest species of toucan and has a distinctive appearance, with a black body, a white throat, chest and uppertail-coverts, and red undertail-coverts. Its most conspicuous feature is its huge beak, which is yellow-orange with a black base and large spot on the tip. It is endemic to South America, where it has a wide distribution from the Guianas south to northern Argentina and Uruguay, and its range has recently been expanding southwards. Unlike other toucans, which inhabit continuous forests, toco toucans inhabit a variety of semi-open habitats at altitudes of up to 1,750 m (5,740 ft). They are especially common in the Brazilian cerrado, gallery forests, and the wetlands of the Pantanal.
Toco toucans mainly feed on fleshy fruits, but also supplement their diets with insects, eggs, and the nestlings of other birds. They will eat any available sugar-rich fruits, and show a high level of variation in their diet depending on the surrounding habitat. Breeding is seasonal, with the timing of the breeding season differing between regions. Nests are usually made in hollows in trees and contain two to four eggs; both parents incubate the eggs for 17–18 days before hatching. It is considered to be of Least Concern by BirdLife International.
