Population justification: The total population is likely to be fewer than 500 pairs, assuming that there are currently unknown populations remaining elsewhere, but may now be considerably fewer than 200 pairs (Wang Ruiqing and Li Fei 2008). It is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. National population sizes have been estimated at c.100-10,000 breeding pairs, c.50-1,000 individuals on migration and c.50-1,000 wintering individuals in China and < c.100 breeding pairs and < c.50 individuals on migration in Korea (Brazil 2009). |
|
Trend justification: Although a series of accurate population surveys are lacking, reports of extremely rapid declines in many locations where the species was formerly abundant suggests a decline of 50-79% over 11 years (three generations) (Wang Ruiqing and Li Fei 2008). |
