Population justification: The global population is estimated to number c.170,000-220,000 individuals (Wetlands International 2015). The European population is estimated at 17,000-26,500 pairs, which equates to 33,900-53,100 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is uncertain, as some populations are decreasing, while others have unknown trends (Wetlands International 2015). The European population trend is unknown (BirdLife International 2015).
