Population justification: The European population is estimated at 980-1,400 calling or lekking males, which equates to 2,000-2,800 mature individuals or 3,000-4,200 individuals (BirdLife International 2015). Wetlands International (2015) estimates the population size of subspecies obscura to be 10,000-25,000 individuals and subspecies affinis at 1-10,000 individuals. Population estimates for the remaining four races are not known. National population estimates include 10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; 100-10,000 breeding pairs, 50-1,000 individuals on migration and < 50 wintering individuals in Japan; and 10,000-100,000 breeding pairs and 1,000-10,000 individuals on migration in Russia (Brazil 2009). The global population is here placed in the band 500,000-999,999 mature individuals, but this requires confirmation.

Trend justification: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes.
