Population justification: The global population size has not been quantified, though national population sizes have been estimated at c.100-100,000 breeding pairs in China and c.1,000-10,000 individuals on migration and c.1,000-10,000 wintering individuals in Taiwan, China (Brazil 2009).

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