Humboldt's whitefronted capuchin (Cebus albifrons) is a species of gracile capuchin monkey. It is found in Colombia, Venezuela, Brazil, and potentially the island of Trinidad.
It prefers primary forest but is also found in various types of secondary forest. It tends to prefer moister and less disturbed forest than other capuchin species.
They have grayish brown fur on the back with darker limbs and yellowish brown hands and feet. The front is cream colored. Their face is pink and they have a dark brown wedgeshaped cap which is clearly separated from the lighter forehead.
The diet is varied, including fruits, insects, insect larvae, other invertebrates, reptiles such as lizards, birds, bird eggs, small mammals, flowers, nectar, honey, leaves, nuts, palms, stems, seeds and tree frogs. Humboldt's whitefronted capuchin has been known to rub or bang food items against hard surfaces. It sometimes associates with squirrel monkeys, tufted capuchins, brown woolly monkeys and Venezuelan red howler monkeys. Both the Humboldt's squirrel monkey and the Ecuadorian squirrel monkey live within the range of Humboldt's whitefronted capuchin. Predators include the blackandwhite hawkeagle, the ornate hawkeagle, the tayra and the harpy eagle.
