Population justification: The global population is estimated to number > c.300,000 individuals (Wetlands International 2015). The European population is estimated at 500-1,000 pairs, which equates to 1,000-2,000 mature individuals (BirdLife International 2015). 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 global population trend is unknown (Wetlands International 2015) as is the European trend (BirdLife International 2015).
