Population justification: The global population size has not been quantified, but the species is reported to be not uncommon in Central Asia, fairly common in the western Himalayas and uncommon in China (Harrap and Quinn 1996).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
