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]
Hornbills in the genus Buceros include some of the largest arboreal hornbills in the world, with the largest being the great hornbill.All the hornbills in this genus have a large and hollow bony casque on their upper beak that can be useful to scientists and bird watchers to recognise their age, sex and species.
