Toucans are birds in the family Ramphastidae in the order Piciformes. There are currently 43 extant species of toucans recognised by the International Ornithologists' Union.^[1]

Conventions

Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the toucan’s range is provided. Ranges are based on the IOC World Bird List for that species unless otherwise noted. Population estimates are of the number of mature individuals and are taken from the IUCN Red List.

This list follows the taxonomic treatment (designation and order of species) and nomenclature (scientific and common names) of version 13.2 of the IOC World Bird List.^[1] Where the taxonomy proposed by the IOC World Bird List conflicts with the taxonomy followed by the IUCN^{[lower-alpha 1]} or the 2023 edition of The Clements Checklist of Birds of the World,^[3] the disagreement is noted next to the species's common name (for nomenclatural disagreements) or scientific name (for taxonomic disagreements).

Classification

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.

Family Ramphastidae

• Genus Aulacorhynchus: eleven species
