Population [top]
Population: The global population size has not been quantified, but the species is described as rare in China and Russia, relatively common in Korea, uncommon in Japan and locally uncommon to common throughout its non-breeding range (Harris and Franklin 2,000). Brazil (2009) estimates that there are: c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Korea; < c.100 breeding pairs and < c.50 individuals on migration in Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).
Trend Justification: This population is estimated to be declining on the basis of marked declines in Russia and Japan from the 1960s to the 1990s at least (Harris and Franklin 2000).
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Unknown

? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
