Population justification: The global population is estimated to number > c.10,000 individuals (Ferguson-Lees et al. 2001), 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).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction (Ferguson-Lees and Christie 2001).
