Population justification: The global population is estimated to number c.23,000 individuals (Bamford et al. in prep), while national population sizes have been estimated at < c.100 breeding pairs and < c.10,000 individuals on migration in China and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).

Trend justification: There are no data on population trends; however, the species is probably in decline owing to pollution and development on the wintering grounds. In the future, these declines may be intensified by habitat shifts on the breeding grounds, caused by global warming.
