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). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 9.1% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
