Population justification: The global population size has not been quantified, but the species is reported to be locally common (Baker 1997), while national population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan; c.10,000-100,000 breeding pairs and c.50-10,000 individuals on migration in Korea; < c.1,000 individuals on migration and < c.1,000 wintering individuals in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
