Population justification: In Europe, the breeding population is estimated to number c.19,800-53,000 breeding pairs, equating to c.39,700-106,000 mature individuals (BirdLife International 2015). Europe forms approximately 15% of the global range, so a very preliminary estimate of the global population size is c.265,000-710,000 mature individuals, although further validation of this estimate is needed. The population is therefore placed in the band 250,000-749,999 mature individuals.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. The European population size is estimated to be fluctuating (BirdLife International 2015).
