Population justification: The population is estimated to number 1,200,000 individuals.
Trend justification: The overall trend is increasing, although some populations may be stable (Wetlands International 2006). This species has undergone a large and statistically significant increase over the last 40 years in North America (4300% increase over 40 years, equating to a 157% 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.
