Population justification: The global population is estimated to number c.400,000-1,500,000 individuals (Wetlands International 2015). The European population is estimated at 46,500-135,000 pairs, which equates to 93,000-270,000 mature individuals (BirdLife International 2015).

Trend justification: The overall population trend is stable (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). Note, however, that these surveys cover less than 50% of the species's range in North America. The European population trend is estimated to be stable (BirdLife International 2015).
