Population justification: The global population is estimated to number c.190,000-410,000 individuals (Wetlands International 2015). The European population is estimated at 36,000-53,000 pairs, which equates to 71,900-106,000 mature individuals (BirdLife International 2015). National population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.100-10,000 breeding pairs, c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Korea and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Japan (Brazil 2009).

Trend justification: The overall population trend is decreasing, although some populations have unknown or increasing trends (Wetlands International 2015). In Europe, the population size trend is unknown (BirdLife International 2015).
