Population justification: (Rich et al. 2004)
Trend justification: This species has undergone a large and statistically significant increase over the last 40 years in North America (155% increase over 40 years, equating to a 26.3% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
