Population justification: The global population is estimated to number c.25,000-100,000 individuals (Wetlands International 2006), while the population in Russia has been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration (Brazil 2009).
Trend justification: The population trend is difficult to determine because of uncertainty over the extent of threats to the species (del Hoyo et al. 1996).
