Population justification: In Europe, the breeding population is estimated to number 41,000,000-59,500,000 pairs, which equates to 81,900,000-119,000,000 mature individuals (BirdLife International 2015). It is therefore likely that the global population falls in the band 10,000,000-500,000,000 mature individuals.

Trend justification: In Europe, trends between 1980 and 2013 show that populations have undergone a moderate increase (EBCC 2015).
