White-faced Capuchin monkeys are very aggressive making threatening gestures and breaking branches as you approach. If they can, they will splash you as you go under their "toilet tree". They have prehensile tails and eat lizards, eggs, nestlings, insect grubs and oysters. New World monkeys have broad noses and wide nostrils. (Old World Monkeys have narrow noses and their nostrils point down.)
