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.100,000 breeding pairs and < c.1,000 individuals on migration in Taiwan; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Korea and < c.50 individuals on migration in Japan (Brazil 2009).
Trend justification: The population is suspected to be in slow decline based on past trends in some populations from 1990 to 2000 (BirdLife International 2004) and owing to continued habitat loss and degradation.
