| Population justification: The global population is estimated to number c.180,000-1,100,000 individuals (Wetlands International 2006), while national population sizes have been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Taiwan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Japan (Brazil 2009). | ||||
| Trend justification: Although Wetlands International consider the population trend to be unknown, the population is suspected to be stable in the absence of evidence for any declines or substantial threats. | ||||
