Population justification: In Europe, the breeding population is estimated to number 7,480,000-14,600,000 pairs, which equates to 15,000,000-29,300,000 mature individuals (BirdLife International 2015). Europe forms 45% of the global range, so a very preliminary estimate of the global population size is 33,000,000-65,100,000 mature individuals, although further validation of this estimate is needed.

Trend justification: In Europe, trends between 1980 and 2013 show that populations have undergone a moderate increase (EBCC 2015). The overall population trend is suspected to be stable in the absence of evidence for any declines or substantial threats.
