Population justification: The population size has not been quantified, but the species is described as uncommon (Carroll et al. 2020). In Colombia it has been inferred that the species may occur at a similar density to its congener O. hyperythrus (26 individuals/km²; Renjifo et al. 2016). Assuming that this density is representative for the entire range and further assuming that only 40% of forests within the range are occupied to account for its rarity (i.e., 4,000 km²; Global Forest Watch 2022), the global population may number 104,000 individuals. This roughly equates to 70,000 mature individuals; to account for uncertainty the population is here placed in the band 50,000-99,999 mature individuals.

Trend justification: The population trend has not been investigated, but a slow and ongoing decline is suspected on the basis of rates of habitat loss and hunting pressure. Tree cover loss within the range is very low (2% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines may however exceed the rate of tree cover loss due to the additional impacts of forest degradation and of hunting. Tentatively, the rate of decline is here placed in the band 1-19% over three generations.
