Population justification: The global population is estimated to number >200,000 individuals (del Hoyo et al. 1992). National population sizes have been estimated at c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Taiwan and c.10,000-100,000 breeding pairs, c.1,000-10,000 individuals on migration and c.1,000-10,000 wintering individuals in Japan (Brazil 2009).
Trend justification: The population is suspected to be in decline owing to disturbance and unsustainable levels of exploitation.
