This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

|Population:||The global population is estimated to number 100,000-1,000,000 individuals (Wetlands International 2006), while national population estimates include: c.100-10,000 breeding pairs in Taiwan; c.100-10,000 breeding pairs and < c.1,000 wintering individuals in Korea and c.100-100,000 breeding pairs in Japan (Brazil 2009).|
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
|Current Population Trend:||Stable|
