Population justification: The global population is estimated to number c.16,000,000-36,000,000 individuals (del Hoyo et al. 1996), while the population in Russia has been estimated at < c.100 breeding pairs and < c.50 individuals on migration (Brazil 2009).
Trend justification: The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007).
