Population justification: The global population size has not been quantified, but the species is described as fairly common in forest with dense underbrush (Byers et al. 1995), while national population estimates include: c.10,000-100,000 breeding pairs, c.1,000-10,000 individuals on migration and c.50-1,000 wintering individuals in China; < c.1,000 individuals on migration in Taiwan; < c.1,000 individuals on migration in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 6.4% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being 5-9%.
