Population justification: In Europe, the breeding population is estimated to number 430,000-761,000 pairs, which equates to 859,000-1,520,000 mature individuals (BirdLife International 2015). Europe forms c.20% of the global range, so a very preliminary estimate of the global population size is 4,295,000-7,600,000 mature individuals, although further validation of this estimate is needed.

Trend justification: This population is estimated to be in decline following decreases in the southern edge of its range (Madge and Burn 1993). The European population is estimated to be stable (BirdLife International 2015).
