Population justification: The global population size has not been quantified, but the species is reported to be locally common (Grewal et al. 2002), while national population sizes have been estimated at c.10,000-100,000 breeding pairs in China and c.100-10,000 introduced breeding pairs in Japan (Brazil 2009). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 7% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species is also traded for the songbird trade. 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.
