Population justification: Delany and Scott (2006) estimate the population to be 300,000 individuals.
Trend justification: The overall population trend is increasing, although some populations have unknown trends (Delany and Scott 2006). This species has undergone a large and statistically significant increase over the last 40 years in North America (712% increase over 40 years, equating to a 68.8% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007) Note, however, that these surveys cover less than 50% of the species's range in North America.
