Population justification: In Europe (which covers >95% of the breeding range), the breeding population is estimated to be 342,000-393,000 breeding pairs, equating to 684,000-785,000 mature individuals or 1,026,000-1,177,500 individuals (BirdLife International 2015). Brooke (2004) also estimated the global population to be at least 1,000,000 individuals.

Trend justification: The overall population trend is unknown. The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007). The European population trend is unknown (BirdLife International 2015).
