Population justification: The global population size has not been quantified, but the species is described as common throughout its range, except for northern Vietnam, where it is rare (del Hoyo et al. 2005), while national population estimates include: c.100-100,000 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.100-100,000 breeding pairs and c.50-10,000 individuals on migration in Japan and c.100-100,000 breeding pairs and c.50-10,000 individuals on migration in Russia (Brazil 2009).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.
