Population justification: The global population size has not been quantified, though national population estimates include: c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).

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