Population justification: In Europe, the breeding population is estimated to number 2,020,000-3,190,000 pairs, which equates to 4,050,000-6,380,000 mature individuals (BirdLife International 2015). Europe forms c.35% of the global range, so a very preliminary estimate of the global population size is 11,570,000-18,230,000 mature individuals, although further validation of this estimate is needed.

Trend justification: The population is suspected to be increasing due to a northward range expansion in the west of its range. In Europe, trends between 1989 and 2013 show that populations have undergone a moderate increase (EBCC 2015).
