Population justification: The global population size has not been quantified, but the species is reported to be generally common throughout most of its breeding range except Pakistan (del Hoyo et al. 1999). National population estimates include: < c.10,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Taiwan; c.100-100,000 breeding pairs and c.50-10,000 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.
