Population justification: The population size is unknown, but the species is described as an uncommon to rare non-breeding visitor to the Malay peninsular, Singapore and the Philippines and a rare non-breeding visitor to Sumatra (del Hoyo et al. 2006), 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 wintering individuals in Taiwan; 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.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 stable in the absence of evidence for any declines or substantial threats.
