Population justification: The population is estimated to number 1,300,000-1,500,000 individuals.

Trend justification: The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006), and in North America the trend is increasing (based on BBS/CBC data: Butcher and Niven 2007).
