Population justification: The global population size has not been quantified, but the species is reported to be locally common (Baker 1997), while the population in China has been estimated at c.100-10,000 breeding pairs, c.50-1,000 individuals on migration and c.50-1,000 wintering individuals (Brazil 2009).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
