Population justification: The population size has not been quantified. Other Crypturellus species vary in density from 1 mature individual/km² (C. variegatus in Peru) to 6 mature individuals/km² (C. undulatus in Brazil; Santini et al. 2018). Assuming that this species occurs at a similar density, and further assuming that c.50% of forests within the range are occupied to account for its preference for hilly and steep terrain (i.e. 1,300 km²; Global Forest Watch 2022), the global population may number 1,300-7,800 mature individuals. This number however requires confirmation and detailed surveys to quantify the population size are essential.

Trend justification: The population trend has not been quantified, but due to its dependence on forest interior a slow decline is suspected on the basis of habitat loss and degradation; moreover, the species may be subject to hunting (Gomes 2020). Tree cover loss is negligible within the known range (1% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, the impacts of habitat degradation and hunting on the population size has not been quantified. It is tentatively suspected that these are causing slow declines at a rate of 1-9% over three generations.
