Subspecies
Often treated as conspecific with Zamboanga Bulbul (Hypsipetes rufigularis), but is much smaller, and no evidence of intergradation where ranges approach each other. Distribution and validity of subspecies provisional. Some are weakly differentiated (e.g. saturatior) and may not warrant recognition, and others possibly represent separate species. A thorough review is required.
