Population justification: The global population is estimated to number c.2,500-9,999 mature individuals, based on recent records and surveys by BirdLife International (2001). This estimate equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. National population estimates include: < c.100 breeding pairs and < c.50 individuals on migration in China, < c.50 individuals on migration and < c.50 wintering individuals in Korea, < c.50 wintering individuals in Japan and < c.100 breeding pairs and < c.50 individuals on migration in Russia (Brazil 2009).
Trend justification: The conversion of wetland habitats is suspected to be driving a moderate decline in this species's population.
