Black-capped Bulbul © alchetron.com

Genus as currently constituted probably polyphyletic. In-depth analysis of morphology, voice, behaviour and genetics required to redefine its limits. Forms a superspecies with Black-crested Bulbul (Pycnonotus flaviventris), Ruby-throated Bulbul (Pycnonotus dispar), Flame-throated Bulbul (Pycnonotus gularis) and Bornean Bulbul (Pycnonotus montis), and all five usually treated as conspecific. All may merit placement in a separate genus, Rubigula. Present species is the most distinct member of the superspecies owing to its short rounded tail with broad white tips, but its other characters (lack of crest, yellow throat, dark iris) are mirrored independently by distant Flame-throated Bulbul (Pycnonotus gularis).

Considered by some authors to be a subspecies of Black-crested Bulbul (Pycnonotus flaviventris).
