Subspecies
No subspecies.
Formerly treated as conspecific with Black-breasted Parrotbill (Paradoxornis flavirostris) by some authors, but is morphometrically quite distinct and differs in vocalizations and, especially, in habitat requirements. Ranges of the two overlap (or formerly overlapped) in parts of north-eastern India, but they are ecologically separated.
Proposed subspecies gongshanensis (from western Yunnan, in southern China) considered of very dubious validity.
