This species has an extremely 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 > c.300,000 individuals (Wetlands International, 2006), while the population in Russia has been estimated at < c.100,000 breeding pairs and < c.1,000 individuals on migration (Brazil 2009).
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).
|Current Population Trend:||Stable|
