Population justification: The global population is estimated to number 625,000-750,000 individuals (Wetlands International 2015). This roughly equates to 415,000-500,000 mature individuals. The European population is estimated at 50,800-68,900 pairs, which equates to 102,000-138,000 mature individuals (BirdLife International 2015).
Trend justification: The overall population trend is increasing, although several populations have unknown trends (Wetlands International 2015). In Europe, the population trend is estimated to be increasing (BirdLife International 2015).
