Population justification: The global population size has not been quantified, but the species is described as rare and local in Nepal, uncommon and local in Bhutan, generally scarce but locally frequent in India, uncommon to locally common in China and generally uncommon to fairly common in its South-East Asian range (del Hoyo et al. 2007). The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.

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