Being largely herbivorous, the buffy saki prefers to forage on seeds, but also feeds on fruit, flowers, nectar, tree bark and very rarely insects (4) (5). It has robust incisors and canines that are perfect for breaking through the tough outer layers of fruit to reach the seeds within (4).
The buffy saki lives in groups of between 3 to 7 individuals, with a home range of between 147 and 204 hectares which may overlap with that of neighboring groups (5). This species appears to spend much of its day resting, and when feeding the buffy saki group often splits into smaller feeding parties (5) (6).
The buffy saki appears to give birth all year round, as births have been recorded in March, June, November and December. Births do not appear to correlate with the fruiting of the trees in the region. The infant is carried on the female’s thigh, and adult colouration is attained after about three weeks, when the infant switches to riding on the back of the female. The young becomes independent after around six months of age (6).
