Population justification: The global population is estimated to be 205,000-295,000 individuals (Wetlands International 2015). The European population is estimated at 56,700-83,000 pairs, which equates to 113,000-166,000 mature individuals (BirdLife International 2015). The population is therefore placed in the band 200,000-299,999 individuals.

Trend justification: 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). Populations elsewhere are stable or unknown. The European population trend is unknown (BirdLife International 2015).
