Population justification: In Europe, the breeding population is estimated to number 2,180,000-4,780,000 pairs, which equates to 4,360,000-9,560,000 mature individuals (BirdLife International 2015).  Europe forms c.20% of the global range, so a very preliminary estimate of the global population size is 21,800,000-47,800,000 mature individuals, although further validation of this estimate is needed.

Trend justification: The population is suspected to be increasing due to a range expansion in the west of its range.  The European population is estimated to be increasing (BirdLife International 2015).
