Population justification: Del Hoyo et al. (1992) estimated the population at several hundred thousand individuals, tentatively placed here in the range 100,000-499,999 individuals, although this could be an underestimate.

Trend justification: The population trend is increasing in North America (based on BBS/CBC data: Butcher and Niven 2007).
