Population justification: The global population is estimated to number > c.2,000,000 individuals (Wetlands International 2006), while the population in Russia has been estimated at c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration (Brazil 2009).
Trend justification: The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006).
