The International Ornithologists' Union (IOU) recognises 43 species of toucans in five genera. [1] This list does not include hybrid species, extinct prehistoric species, or putative species not yet accepted by the IOU.
Toucans (/ ˈ t uː k æ n /, UK: /-k ə n /) are Neotropical birds in the family Ramphastidae. The Ramphastidae are most closely related to the Toucan barbets. They are brightly marked and have large, often colorful bills. The family includes five genera and over 40 different species. Toucans are arboreal and typically lay two to four white ...
Keel-billed toucans have zygodactyl feet (or feet with toes 2 and 3 facing forwards, and toes 1 and 4 facing backwards) – two toes face forward and two face back. Because toucans spend a large portion of time in the trees, this helps the birds to stay on the branches of the trees and jump from one branch to another.
A major taxonomy review in 1974 resulted in 6 species in the genus Aulacorhynchus, [5] and this was adopted by virtually all later authorities. [3] [6] [7] [8] [9]In 2001, it was suggested that A. prasinus, as traditionally defined, was a species complex that should be split into 7 different species based on preliminary morphological evidence.

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 ...
Andigena, the mountain toucans, is a genus of birds in the family Ramphastidae. They are found in humid highland forests in the Andes of South America, ranging from Bolivia to Venezuela. These medium-sized toucans all have olive-brown upperparts, a black crown, yellow rump, blue-grey underparts and a red vent.
Toucans are near passerine birds from the Neotropics. They are brightly marked and have enormous colorful bills which in some species amount to half their body length. Eight species have been recorded in Guyana. Toco toucan, Ramphastos toco; White-throated toucan, Ramphastos tucanus; Channel-billed toucan, Ramphastos vitellinus
