Trend justification: The overall population trend is stable, although some populations have unknown trends (Wetlands International 2006). This species has undergone a large and statistically significant increase over the last 40 years in North America (112% increase over 40 years, equating to a 20.7% 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.
