Very little information on the species Lemur catta exists today. Thus, any study concerning them is very important to understanding their full behavioral repertoire. One social behavior that the ringtailed lemurs (L. catta) share with other primates is the phenomenon of male migration or male dispersal. The hypothesis investigated in this study was whether these male immigrants, or non-kin, displayed different social actions or interactions, than those displayed by kin within a group. A troop of twenty-seven semi-free ranging ringtailed lemurs at the Duke University Primate Center in Durham, North Carolina, was studied in comparing the social behaviors of kin and non-kin. Social behaviors and Greeting, and interactions that were documented fell under the categories of: Approaches, Departures, Grooming, Huddling, and Playing. Two immigrants and four males with relatives in the group were studied, and it was found that a difference in behaviours was apparent, especially in the areas of grooming, huddling and agonistic interactions.
