Population justification: The global population has been estimated at 1,400,000 individuals.
Trend justification: Although data indicates a rapid annual decline of 3.8% between 1980 and 2007 (Sauer et al. 2008), the most recent data from the Breeding Birds Survey suggests a more moderate decline of 0.63% per annum between 1998 and 2009 (Sauer in litt. 2010). This equates to a decline of 6.3% over this period, hence a decline of 1-9% over the past 11 years (three generations) is estimated.
