Population justification: The population is estimated at 230,000 individuals.
Trend justification: The overall trend is decreasing (Delany and Scott 2006). In North America, this species has undergone a large and statistically significant increase over the last 40 years (168% increase over 40 years, equating to a 28% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
