Population justification: The population size of this species has not been quantified, but it has been described as locally common.

Trend justification: An analysis of deforestation between 2000 and 2012 estimated forest loss within the species's range at a rate equivalent to 36.7% over three generation lengths (28 years) (Tracewski et al. 2016). Whilst the species may be tolerant of some habitat degradation and secondary habitats, it is also severely threatened by hunting, and its actual rate of population decline is likely greater than the estimate decline based on forest loss alone. Thus, the rate of decline is placed in the band 30-49% over three generations. Assuming the recent rate of decline remains constant, the species is projected to decline by 30-49% over three generations.
