Population justification: The global population is estimated to number > c.160,000 individuals (Wetlands International, 2006), while the population in Russia has been estimated at c.100-100,000 breeding pairs and c.50-10,000 individuals on migration (Brazil 2009).

Trend justification: Although Wetlands International consider the current population trend to be unknown, it is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 1996).
