Population justification: The global population is estimated to number c.25,000-100,000 individuals (Wetlands International, 2006), while national population sizes have been estimated at < c.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 stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).
