Population justification: The global population size has not been quantified directly. Based on density estimates of similar-sized congeners (C. cinereus: 3 mature individuals/km² in Peru; C. undulatus: 3 mature individuals/km² in Peru; Santini et al. 2018) and assuming that around 10% of the mapped range is occupied (i.e. 10% of 296,000 km²), the total population may number 88,800-296,000 mature individuals, rounded here to 80,000-300,000 mature individuals. The species is described as 'fairly common but patchily distributed' (Stotz et al. 1996).

Trend justification: The population trend has not been assessed directly. Forest loss over the past three generations (17.4 years) has been low within the range (potentially <10%; Global Forest Watch 2020). The species is however susceptible to fragmentation and disturbance, and is additionally threatened by hunting (A. Lees in litt. 2011, Cabot et al. 2020). As such, the rate of population decline may be larger than the rate of forest loss, and the species is tentatively assessed as declining at a rate of 10-19% over three generations.
