Population & trend

| Population justification: The global population is estimated to number > c.25,000 individuals (Wetlands International, 2006), while national population estimates include: c.50-10,000 individuals on migration in China; c.50-10,000 wintering individuals in Taiwan; c.50-10,000 individuals on migration in Korea; c.50-1,000 individuals on migration and < c.1,000 wintering individuals in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009). | ||||
| Trend justification: The population trend is difficult to determine because of uncertainty over the extent of threats to the species. | ||||
