Population justification: The global population is estimated to number c.620,000-700,000 individuals (Wetlands International 2015). The European population is estimated at 25,100-50,100 pairs, which equates to 50,100-100,000 mature individuals (BirdLife International 2015). National population estimates include: c.1,000-10,000 individuals on migration and c.1,000-10,000 wintering individuals in China; c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan, China; c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in Korea; c.1,000-10,000 individuals on migration and c.50-10,000 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 overall population trend is uncertain, as some populations are decreasing, while others are increasing, stable or have unknown trends (Wetlands International 2015). This species has had stable population trends over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Note, however, that these surveys cover less than 50% of the species's range in North America. The European population trend is unknown (BirdLife International 2015).
