This species is common. The density of C. olivaceus in the Voltzberg Study area in Surinam was estimated by Mittermeier (1977) to be about 4 individuals/km². At the Nourague Field Station in French Guiana, C. olivaceus is much rarer than Cebus apella. Guillotin et al. (1993) estimated densities of 2/km² and a biomass of 6.3 kg/km², compared with 29.1/km² and a biomass of 86.9 kg/km² for the tufted capuchins. The only other density data for this species comes from Guyana, where Muckenhirn et al. (1975) found a range of 1.8-22.2 animals/km² in five different localities.
