Female great hornbill Hornbills are birds in the families Bucerotidae and Bucorvidae. There are currently 62 extant species of hornbills recognised by the International Ornithologists' Union, two in Bucorvidae and 60 in Bucerotidae. Many species of fossil hornbills are known from the Miocene onwards; however, their exact number and taxonomy are unsettled due to ongoing discoveries. Conventions ...

The eastern long-tailed hornbill (Horizocerus cassini) is a species of bird in the hornbill family Bucerotidae found in humid forests of West Africa. It was formerly considered to be conspecific with the western long-tailed hornbill ( Horizocerus albocristatus ) with the English name "white-crested hornbill".
The wreathed hornbill is a monotypic taxon and is widely recognized as a member of Rhyticeros, the genus of hornbills with low wreathed casques. [6] Analysis of the mitochondrial genomes of eight hornbill species revealed that the wreathed hornbill is closely related with Aceros and the Visayan hornbill (Penelopides panini). [7]
Recent genetic data show that ground hornbills and Bycanistes form a clade outside the rest of the hornbill lineage. [6] They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia.
