Population justification: The global population is estimated to number c.150,000,000 individuals (Rich et al. 2004). The European population is estimated at 5,340,000-12,700,000 pairs, which equates to 10,700,000-25,300,000 mature individuals (BirdLife International 2015). Europe forms approximately 15% of the global range, so a very preliminary estimate of the global population size is 71,000,000-169,000,000 mature individuals, placed in the range 50,000,000-199,999,999 mature individuals, although further validation of this estimate is needed.

Trend justification: This species has undergone a small or statistically insignificant increase over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). The European population trend showed a moderate decline between 1980 and 2013 (EBCC 2015).
