Population justification: The global population is estimated to number > c.18,000,000 individuals (del Hoyo et al. 1996). The European population is estimated at 2,350,000-3,060,000 mature individuals (BirdLife International 2015).

Trend justification: The population trend is increasing in North America (based on BBS/CBC data: Butcher and Niven 2007). Although a number of populations are increasing, including in the UK (which holds nearly half the European population) since 2000 (JNCC 2014), a recent sharp decline was observed in Iceland (where nearly a quarter of the European population is found) since 2005. As a result of the reported decline in Iceland, the estimated and projected rate of decline of the European population size over the period 2005-2050 (three generations) varies from 25% to more than 50% (BirdLife International 2015).
