The International Ornithologists' Union (IOU) recognises 62 species of hornbills in across two families and fifteen genera. Where the taxonomy proposed by the IOC World Bird List conflicts with the taxonomy followed by the IUCN or the 2023 edition of The Clements Checklist of Birds of the World, the disagreement is noted next to the species's common name (for nomenclatural disagreements) or scientific name (for taxonomic disagreements).

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. Population estimates are of the number of mature individuals and are taken from the IUCN Red List. Ranges are based on the IOC World Bird List for that species unless otherwise noted. Range maps are provided wherever possible if a range map is not available, a description of the hornbill's range is provided. Rhinoceros hornbills are typically found in primary, lowland rainforests, hill dipterocarp forests, mountainous forests, and swamp forests within elevations of 130 to 1500 meters.

Many species of fossil hornbills are known from the Miocene onwards however, their exact number and taxonomy are unsettled due to ongoing discoveries.Ĭonventions IUCN Red List categories Conservation statusĬonservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. The Rhinoceros Hornbill is one of the largest hornbills. There are currently 62 extant species of hornbills recognised by the International Ornithologists' Union, two in Bucorvidae and 60 in Bucerotidae.
