This species is often found in the lower understory of submontane and montane forest, and spends ~50% of its time foraging on the forest floor (Ehardt et al. 2005; Ehardt and Butynski 2006). It frequently moves through and utilizes disturbed areas and mosaic habitat (Ehardt et al. 2005). Diet is strongly concentrated on fruit, nuts and seeds, as well as herbaceous material (Ehardt et al. 2005). Mean group sizes range from 15 to >40 animals (Wasser 1993; Ehardt 2001; Ehardt et al. 2005).
