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; Genus Pteroglossus: fourteen species; Genus Selenidera: six species
The lettered aracari is the smallest species of toucan. 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).
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. .

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 December 2019, the International Union for Conservation of Nature (IUCN) listed 8460 least concern avian species. [1] Of all evaluated avian species, 76.9% are listed as least concern. No subpopulations of birds have been evaluated by the IUCN. This is a complete list of least concern avian species evaluated by the IUCN.
