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