Population justification: A population size of 46,000-295,000 individuals was estimated by Lambert (1993a, b) although subsequent work in 1994 suggests the population may at that time have been considerably higher.
Trend justification: Data from the UNEP-WCMC CITES trade database shows that legal trade declined through the 1990s and ceased in 2003, with an average of 1915 birds taken per year between 1984-2008 (three generations). Poaching figures of around 2,800 birds were recorded in 2007 (Anon, 2008). Assuming an average rate of 5,000 birds taken annually for trade (legal and illegal), and based on the 1992 population estimate of 45,000-300,000 individuals a decline of 34%-95% over 25 years (three generations) may have occurred; however, based on density estimates of up to 149 birds/km2 the population is now thought to have been significantly underestimated, and taking this into account a decline of 30-50% over three generations is estimated to have taken place.
