Population justification: The global population size has not been quantified, but the species is described as locally abundant in its breeding range and locally rather common in Thailand during its non-breeding season (del Hoyo et al. 2006), while the population in China has been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration (Brazil 2009). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

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