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 massive beak, which is yellow-orange with a black base and ...
The toucan beak has a synergistic sandwich structure with a thin rigid outer shell encapsulating the bulk of the volume which is a cellular solid. [1] The exterior layer, known as the rhamphotheca, is composed of several layers of overlapping sheets of beta keratin. [1]
Toucans range in size from the lettered aracari (Pteroglossus inscriptus), at 130 g (4.6 oz) and 29 cm (11 in), to the toco toucan (Ramphastos toco), at 680 g (1.50 lb) and 63 cm (25 in). Their bodies are short (of comparable size to a crow's) and compact. The tail is rounded and varies in length, from half the length to the whole length of the ...
The phylogenetic relationships among toucans have been the subject of ongoing debate and research; in the past, the eight toucan species were classified into different subfamilies based on their bill size and shape. However, recent molecular studies have suggested that toucans are more closely related to aracaris and toucanets than previously ...
In captivity it is the most frequently bred member of the toucan family and is the most popular as a tame hand-fed pet. It requires a large cage and toys to prevent boredom due to its active nature, and a high-fruit diet. When all these requirements are met it is an affectionate companion for many years.

The chestnut-mandibled toucan is a resident breeder in moist lowland forest. The 2–4 white eggs are laid in an unlined cavity high in a decayed section of a living tree, or occasionally in an old woodpecker nest in a dead tree. Both sexes incubate the eggs for at 14–15 days, and the toucan chicks remain in the nest after hatching.

Ramphastides is an infraorder of the order Piciformes that includes toucans and barbets. Formerly, the barbets have been classified in a single family, the Capitonidae . [ 1 ] However, this has turned out to be paraphyletic with regard to toucans, which resulted in the Capitonidae being split into several families.
