Population justification: The global population size has not been quantified, but the species is generally described as uncommon in the Philippines, rare on the Chinese mainland, common on Taiwan and scarce on the Kurile islands and Sakhalin (Feare and Craig 1998). National population estimates include: c.50-1,000 individuals on migration and < c.50 wintering individuals in Taiwan; c.100-100,000 breeding pairs and c.50-10,000 individuals on migration in Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).

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