Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is apparently common through much of its range. However, its status and population trend is very poorly known (del Hoyo et al. 1996). National population estimates include: c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China; < c.1,000 individuals on migration in Korea and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009). The population is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).
