Subspecies
No subspecies.
Paradoxornis gularis (Sibley and Monroe 1990, 1993) has been split into Grey-headed Parrotbill (Psittiparus gularis) and Black-headed Parrotbill (Psittiparus margaritae) following Collar (2006).
Until recently considered conspecific with Grey-headed Parrotbill (Psittiparus gularis), but the two differ somewhat in morphology, plumage and voice.
