Population justification: The population is estimated to number 2,000,000 individuals.

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