Population justification: The European population is estimated at 84,100-252,000 pairs, which equates to 168,000-505,000 mature individuals (BirdLife International 2015). Europe forms c. 5% of the global range, so a very preliminary estimate of the global population size is 3,360,000-10,100,000 mature individuals, although further validation of this estimate is needed. The population is therefore placed in the band 3,000,000-10,499,999 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 is estimated to be increasing (BirdLife International 2015).
