Population justification: The global population size has not been quantified, but the species is reported to be from common (various localities in China) to scarce and local in the eastern Himalayas (Harrap and Quinn 1996), while the population in China has been estimated at c.100-10,000 breeding pairs (Brazil 2009).
Trend justification: The population is estimated to be increasing following recorded range expansions (del Hoyo et al. 2007).
