Population justification: The global population is estimated to number c.130,000-2,000,000 individuals (Wetlands International 2006), while 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 in Taiwan and c.100-10,000 breeding pairs in Japan (Brazil 2009).

Trend justification: The overall population trend is stable, although some populations have unknown trends (Wetlands International 2006).
