Black-crested Bulbul

The black-crested bulbul (Rubigula flaviventris) is a member of the bulbul family of passerine birds. It is found from the Indian subcontinent to southeast Asia. == Taxonomy and systematics == The black-crested bulbul was originally described in the genus Vanga and later moved to the genus Pycnonotus. Pycnonotus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbuls, including the black-crested bulbul, were moved to Rubigula. Until 2008, the black-crested bulbul was considered as conspecific with the black-capped, ruby-throated, flame-throated and Bornean bulbuls, but these are all now treated as distinct. === Subspecies === Eight subspecies are accepted: R. f. flaviventris – (Tickell, 1833): Found from Nepal, northern and eastern India (including Pachmarhi in central India) to southern China and central Myanmar R. f. vantynei – Deignan, 1948: Found from eastern and southern Myanmar to southern China and northern Indochina R. f. xanthops – Deignan, 1948: Found in south-eastern Myanmar and western Thailand R. f. auratus – Deignan, 1948: Found in north-eastern Thailand and western Laos R. f. johnsoni – (Gyldenstolpe, 1913): Originally described as a separate species.
