The back and prehensile tail are black. The main canopy is preferred. Infants are born with a gray face and ears but look like the adults by 3 months.
Males defend the territory.
Males emigrate and may remain solitary before joining another group. Diurnal and arboreal. White-throated capuchins, like many primates, enhance the health of the forest by pollinating some plants and dispersing the seeds of others. When they eat the buds of Gustavia simaruba, branching of the tree increases, enhancing fruit production. Males forage near or on the ground for large vertebrates and invertebrates.
