Population justification: Brooke (2004) estimated the global population to number c.3,000,000 individuals, while national population estimates include: c.100-10,000 breeding pairs, c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in China; c.100,000-1,000,000 breeding pairs, c.10,000 individuals on migration and c.10,000 individuals on migration and c.50-1,000 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 undergoing a moderately rapid decline, owing primarily to predation by introduced mammals (S. Uematsu in litt. 2012).
