Population justification: The population is estimated to number 4,000,000-9,850,000 individuals. The European population is estimated at 76,100-92,300 pairs, which equates to 152,000-185,000 mature individuals (BirdLife International 2015). The population is therefore placed in the band 4,000,000-9,999,999 individuals.

Trend justification: The overall population trend is increasing, although some populations may be stable, decreasing or have unknown trends (Wetlands International 2015). This species has undergone a small or statistically insignificant decrease 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 is estimated to be decreasing by less than 25% in 24.3 years (three generations) (BirdLife International 2015).
