Population justification: The population size is unknown, but the species is described as rare to fairly common (del Hoyo et al. 2006), while the population in China has been estimated at < c.100 breeding pairs and < c.50 individuals on migration (Brazil 2009).

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