Population justification: The global population is estimated at c. 410,000 individuals (Wetlands International 2015). The European population is estimated at 57,000-74,000 pairs, which equates to 114,000-148,000 mature individuals (BirdLife International 2015).
Trend justification: The overall trend is suspected to be increasing (Wetlands International 2015). In Europe the population size is estimated to be increasing (BirdLife International 2015).
