Population justification: The total population is estimated to number 1,500-3,000 individuals, roughly equivalent to 1,000-2,000 mature individuals (Martins-Ferreira in litt. 2007).
Trend justification: A very rapid and on-going population decline is suspected owing to chronic exploitation for the bird trade as well as habitat loss and fragmentation.
