Population justification: The global population is estimated to number > c.16,000,000 individuals (Rich et al. 2004). The European population is estimated at 611,000-1,160,000 pairs, which equates to 1,220,000-2,320,000 mature individuals (BirdLife International 2015).

Trend justification: This species has undergone a large and statistically significant increase over the last 40 years in North America (166% increase over 40 years, equating to a 27.7% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). In Europe, trends between 1980 and 2013 show that populations have undergone a moderate increase (EBCC 2015).
