Population justification: The global population has been estimated to number c.4,800,000-8,900,000 individuals (Wetlands International 2015). The European population is estimated at 1,340,000-1,990,000 pairs, which equates to 2,670,000-3,980,000 mature individuals or 4,000,000-5,970,000 individuals (BirdLife International 2015). Combining the new figures for the European population (BirdLife International 2015) with estimates from the other populations in Wetlands International (2015) provides an overall estimate of 4,400,000-8,200,000 individuals. National population estimates include: > c.1,000 individuals on migration and > c.1,000 wintering individuals in China; c.1,000-10,000 individuals on migration and > c.1,000 wintering individuals in Taiwan; > c.1,000 individuals on migration and > c.1,000 wintering individuals in Korea; < c.10,000 individuals on migration and c.1,000-10,000 wintering individuals in Japan and c.10,000-1 million breeding pairs and > c.1,000 individuals on migration in Russia (Brazil 2009).

Trend justification: The overall population trend is unclear. Some populations have unknown trends (Wetlands International 2015). This species has undergone a large and statistically significant increase over the last 40 years in North America (361% increase over 40 years, equating to a 46.6% increase per decade; 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. Between 1990 and 2013 the European population is estimated to have declined moderately (EBCC 2015).
