Population justification: In Europe, the breeding population is estimated to number 683,000 pairs, which equates to 1,370,000 mature individuals (BirdLife International 2015). Europe forms 75-94% of the global range, so the global population size is estimated at 1,500,000-1,800,000 mature individuals, although further validation of this estimate is needed.

Trend justification: In North America, the population trend is increasing (based on BBS/CBC data: Butcher and Niven 2007). The European population is also estimated to be increasing (BirdLife International 2015).
