Platyrrhine Natural Life and Histories
In the Peruvian Forest there are two species of Capuchins that have two really different eating and mating habits. The white fronted capuchins do not fight over food and eat in the order of arrival at the feeding site. In brown capuchin societies the dominant male is the first to eat while others wait while he finishes. When defending their food, in brown capuchin societies only the dominant male fights while white capuchins fight as a group. Although their feeding behavior is alike, brown capuchin monkeys can eat tougher fruits and hard seed while white fronted capuchins have trouble opening hard clusters. This explains why brown capuchins feed in small trees that are common in the forest, while white fronted capuchins feed in tall trees with more fruit. Since the tall trees have more fruit white fronted capuchins can eat all together. Fighting over food only occurs when there is a limited supply. White fronted capuchins fight less because they eat in bigger trees with more fruit. In brown capuchin societies, when in estrus females run after the dominant male for a while until mating. The female pursues the dominant male because she wants his protection after her babies are born. In white capuchin societies the male pursues the female the female doesn’t always pick the dominant male for mating. This is because they feed in large trees and her offspring will probably survive without the males’ protection.
White uakaris are rare monkeys that live in Brazil. Uakaris have long fur, short tails, red bald faces, powerful jaws, and specialized teeth. They live a 3,100 island surrounded by waters of the Japura and Amazon rivers. They eat mostly the pulp and seeds of fruit. Ukaris live in large groups of fifty monkeys. They wake-up as soon as the sun rises and eat, during the hottest part of the day they nap and then feed until sundown. Every year the forests are flooded, so the monkeys escape to the tops of trees. They do...
