Population justification: The total breeding population was estimated at 2,800 pairs (5,600 mature individuals) in 2006. This roughly equates to 8,400 individuals in total.
Trend justification: The overall rate of decline between 1990 and 2006 was 4.3% per year, equivalent to a decrease of 52.9% over three six-year generations (Kemper et al. 2007).
