Population justification: The species occurs very patchily and is absent from areas of apparently suitable habitat. It's global population is precautionarily estimated to lie within the band 1,000-3,000 individuals (C. Trainor in litt. 2012), roughly equivalent to 660-2,000 mature individuals.
Trend justification: The on-going clearance of lowland forest and widespread hunting pressure are suspected to be driving a rapid and continuing decline in this species's population.
