Population justification: 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).
