Population justification: The global population is estimated to number c.4,600,000-6,500,000 individuals (Wetlands International, 2006), while national population estimates include: < c.10,000 individuals on migration and > c.10,000 wintering individuals in China; > c.1,000 individuals on migration and > c.1,000 wintering individuals in Taiwan; > c.1,000 individuals on migration and c.50-1,000 wintering individuals in Korea; > c.1,000 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 decreasing, although some populations are stable or have unknown trends (Wetlands International 2006). 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).
