RESUMO

The eating behavior of the primates is directly related to the enviromenment which they are in, so it is extremely important their study to search new contribuitions to understand the ecological behavior of this animals. In the way, with the objective of studying the eating and the forage behavior verifying the different during the seasons and the months to quantify the items eaten, forage substrata and the use of verticak space, a group pf Capuchin Monkeys (Cebus apella) was studied during the period of January 2006 to January 2007, considering a total of 67 observation days with 1881 scan sampling and 5136 behavior registers, it corresponds to 470,25 hs of direct observation of the animals. During the collect os data about the eating behavior and the forage it was used the method of scan sampling during five breaks of ten minutes. Considering the eating habit, 1114 registers were collected, it represents 21,69 % of all activities done by the animals. The food eaten by group were fruit and seeds (70,61%, n=723), foliages connecting rods (14,45%, n 148), nectar (6,64%, n=68), honey (1,46%, n 15), invertebrates (5,27%, n=54) and vertebrates ( 0,88%, n=9), the fruit and seeds were mor eaten during the whole research period comparing with the other items, however the season period analyses showed that there were a strong difference only in the invertebrate consumption and foliages connecting rods. Relating to the forage behavior, the animals studied look more for trunks, fruit and soil, presenting the following frequencies: 44,22% (n=830), 5,54% (n= 46), 28,92% (n= 240), and 21,33% (n= 177). When it was analyzed the vertical space where the behavior analyzed was more presented, we found the highs of 0,10 to 5,99 meters and 6 to 10,99 meters where the animals forage and at more. The results of this research will provide comparative perspectives on capuchim monkeys (Cebus apella) eating and the forage behavior in fragment of Scrub, and will contribute to the development of conservation for this species and yours endangered ecosystem.
