Population justification: The global population size has not been quantified, but the species is reported to be not uncommon (MacKinnon and Phillipps 2,000), while national population estimates include: c.10,000-100,000 breeding pairs in China; c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan and < c.1,000 individuals on migration and < c.1,000 wintering individuals in Japan (Brazil 2009).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
