Population justification: The global population is estimated to number >1,000,000 individuals (del Hoyo et al. 1992). National population sizes have been estimated at <100 breeding pairs and <50 individuals on migration in Taiwan and <100 breeding pairs and <50 individuals on migration in Japan (Brazil 2009).

Trend justification: The population is suspected to be in decline owing to habitat loss, predation by invasive species and unsustainable levels of exploitation.
