Population & trend

	Estimate	Data quality	Derivation	Year of estimate
No. of mature individuals	600-1700	poor	Estimated	2000
Population trend	Decreasing	poor		-
Number of subpopulations	2-100	-	-	-
Largest subpopulation	51-250	-	-	-
Generation length (yrs)	4.8	-	-	-
Population justification: The population size is preliminarily estimated to fall into the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.
Trend justification: A rapid and on-going population decline is suspected owing to trapping for the bird trade together with widespread habitat loss and degradation.
