Population justification: The global population size has not been quantified, though in Europe, the breeding population is estimated to number 20,200-56,500 pairs, which equates to 40,300-113,000 mature individuals (BirdLife International 2015), with Europe forming c.5% of the global range. National population estimates include: c.10,000-100,000 breeding pairs, 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; c.1,000-10,000 individuals on migration and c.1,000-10,000 wintering individuals in Korea; c.10,000-100,000 breeding pairs, c.1,000-10,000 individuals on migration and c.1,000-10,000 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 population is suspected to be stable in the absence of evidence for any declines or substantial threats. The small European population is estimated to be increasing (BirdLife International 2015).
