Population justification: The global population is estimated to number > c.560,000-650,000 individuals (Wetlands International 2015). The European population is estimated at 1,500-1,800 pairs, which equates to 3,000-3,600 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is uncertain, as some populations are decreasing, while others are stable, have unknown trends or are increasing (Wetlands International 2015). This species has undergone a small or statistically insignificant increase over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). The European population trend is unknown (BirdLife International 2015).
