Population justification: The global population size has not been quantified, but the species is described as common to locally abundant (del Hoyo et al. 2006), while national population estimates include: c.10,000-100,000 breeding pairs and c.50-10,000 individuals on migration in China; c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Korea; c.10,000-100,000 breeding pairs and c.1,000-10,000 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.
