In this study, we explored the behavioral development of wild black and goldhowler monkey infants, Alouatta caraya, in relation to the activity pattern and social behavior. We studied 35 infants of known age, belonging to ll social groups, during 27 months (September 2010) at two nearby sites in northeastern Argentina. We recorded 11 behavioral categories using focal animal and instantaneous point sampling techniques, during 2,266 hours of observation. We found a gradual development pattern, similar to those found in other Alouatta species. Social relationships between infants and other group members were principally affiliative interactions, and mother-offspring relationship was dynamic throughout the development. At 9-10 months, the weaned infants attained the behavioral pattern of adult individuals. In summary, since early age A. caraya individuals exhibit species-specific behaviors that facilitate their inclusion in the groups.
