Population justification: The global population is estimated to number c.25,000-1,000,000 individuals (Wetlands International 2006), while national population sizes have been estimated at c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China and < c.100 breeding pairs and c.50-1,000 individuals on migration in Korea (Brazil 2009).

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