Population justification: The global population size has not been quantified, but the species is reported to be fairly common and widespread (del Hoyo et al. 1997), while national population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Korea and possibly c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend justification:
The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016).
