Population justification: Rich et al. PIF North American Landbirds Conservation Plan (2004).
Trend justification: This species has undergone a large and statistically significant decrease over the last 40 years in North America (-63.8% decline over 40 years, equating to a -22.4% decline per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Declines have been particularly marked over the past 15 years (Buehler et al. 2007).
