Resumo: | The development of the interactions of an infant primate with its mother and the other members of its social group plays a special role in the ethology and demography of the species, with consequences for their survive and their conservation. The objective of the present study is to investigate the development of an infant of Alouatta guariba (Humboldt, 1812) in the wild, its behavior and interactions during its first seven months of age, in a remnant of Araucaria Pine Forest in Paraná State, Brazil. Using the method of instantaneous scanning with 5 min intervals, a total of 46 hours and 15 minutes of direct observation (555 individual records) showed that the infant behavioral patterns during its first four months were characterized by high dependency, which decreased progressively until the appearance of typically juvenile behaviors during the remaining 3 months. The first records of feeding on solid food, tail functionality and allomaternal care were also recorded and discussed. This work contributes to an understanding of the ontogenetic development of a poorly known aspect of this species, and thus for a more understanding of the genus Alouatta Lacépède, 1799.
