Population justification: The population size has not been quantified. The species is described to be uncommon and the population is considered to be "small" (Züchner and Boesman 2020). Based on this evidence and the spatial spread of recent observations within its range (eBird 2022), the population is tentatively suspected to fall into the band of 1,000-2,499 mature individuals. Further research on an accurate population size estimate and subpopulation structure is however urgently required.

Trend justification: Remote sensing data shows that tree cover loss within the species' range equates to <1% over 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species also prefers secondary growth forests and forest edges, which will reduce any vulnerability to habitat alteration. However, the species may be impacted by surrounding habitat degradation as a result of human activities such as burning, agriculture, ranching, mining, and development (SERFOR 2018). Previous research has also shown that parts of the species may be found in local markets (due to believed aphrodisiac abilities), whilst it may also be readily hunted (Garrigues 2000). As such, the overall population is tentatively suspected of declining at a slow rate, placed here in the band of 1-9% over 10 years.
