Population justification: The global population size has not been quantified, but the species is reported to be fairly common in several parts of its range (del Hoyo et al. 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.100 breeding pairs and < c.50 individuals on migration in Taiwan; < c.100 breeding pairs and < c.50 individuals on migration in Korea; c.100-100,000 breeding pairs and c.50-10,000 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).
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
