Population justification: The global population is estimated to number c.16,000,000-36,000,000 individuals (del Hoyo et al. 1996). However the European population alone was recently estimated at 9,200,000-82,000,000 mature individuals (BirdLife International 2015), therefore, the global population is likely to be considerably larger than the current estimate.
Trend justification: The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007). The European population trend is unknown (BirdLife International 2015).
