Population justification: Based on recent surveys within various parts of the species's range, C. Trainor (in litt. 2007) has estimated the global population at fewer than 7,000 individuals: 3,200-5,000 on Sumba, 500 on Komodo, 200-300 on Timor Leste, 200-300 on Sulawesi, 20-50 on West Timor, 40-70 on Flores, 50-100 on Sumbawa, 100 on Rinca and c.700 other birds in total. It is best placed in the band 2,500-9,999 individuals, equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals. |
|
Trend justification: This species has declined rapidly owing to international trade in the species and widespread deforestation within its range. Declines have been documented in recent years, even where trade is not so obvious, such as on Komodo where an estimated decline of 60% occurred between 2000-2005. |
