Population justification: In Europe, the breeding population is estimated to number 2,330,000-3,750,000 pairs, which equates to 4,670,000-7,490,000 mature individuals (BirdLife International 2015). Europe forms c.75% of the global range, so a very preliminary estimate of the global population size is 6,226,000-9,986,000 mature individuals, placed here in the range 6,000,000-9,999,999 mature individuals, although further validation of this estimate is needed.

Trend justification: The population is suspected to be increasing owing to a northerly and easterly range expansion (del Hoyo et al. 2006), although in Europe, trends between 1989 and 2013 have been stable (EBCC 2015).
