Population justification: The global population is estimated at 230,000-2,220,000 individuals (Wetlands International 2015). The European population is estimated at 28,300-37,700 pairs, which equates to 56,500-75,400 mature individuals (BirdLife International 2015). The population is therefore placed in the band 200,000-2,300,000 individuals.

Trend justification: The overall population trend is decreasing, although some populations have stable trends (Wetlands International 2015). This species has undergone a large and statistically significant increase over the last 40 years in North America (3,800% increase over 40 years, equating to a 150% increase per decade; 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. In Europe the population size is estimated to be increasing (BirdLife International 2015).
