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.
