Population justification: The most recent estimate places the global population of mature individuals at <50,000 (Partners in Flight 2019) although this figure is declining rapidly, a trend that is likely to continue (Eisermann et al. 2006).

Trend justification: The area of remaining habitat is declining with a ~6% reduction in forest area recorded throughout its range throughout the past three generations (Tracewski et al. 2016); such trends are likely to continue (Eisermann et al. 2006). Further to habitat alteration, hunting pressures are also a principal threat with both threats increasing owing to an expanding human population. The species is therefore inferred to be declining rapidly, with Brooks (2006) estimating rates of decline of up to 30% every 10 years.
