Population justification: In Europe (which covers c.90% of the breeding range), the breeding population is estimated to be 10,800-25,000 pairs, which equates to 21,500-50,100 mature individuals (BirdLife International 2015). So a very preliminary estimate of the global population size is 23,800-55,600 mature individuals, although further validation of this estimate is needed.

Trend justification: In Europe the population size is estimated to be stable (BirdLife International 2015).
