Population justification: The global population is estimated to number >22,000,000 individuals (del Hoyo et al. 1996). The European population is estimated at 1,920,000-2,840,000 mature individuals (BirdLife International 2015). The population in Russia has been estimated at c.10,000-1 million breeding pairs (Brazil 2009).

Trend justification: In North America, the population is increasing (based on BBS/CBC data: Butcher and Niven 2007). The European population trend is unknown (BirdLife International 2015).
