Taxonomy and systematics
The Bornean bulbul was previously placed in genus Pycnonotus. This genus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbul species, including the Bornean bulbul, moved to Rubigula.Until 2008, the Bornean bulbul was considered as conspecific with the black-capped, black-crested, ruby-throated and flame-throated bulbuls. Some authorities have considered the Bornean bulbul to be a subspecies of the black-capped bulbul.
