Population justification: The global population size has not been quantified. However, the species is reported to be fairly common in the eastern Himalayas but uncommon in the western Himalayas, south-eastern Tibet and south-west China although very numerous in northern Sichuan. (Harrap and Quinn 1996).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
