Relationships among coresident male white-faced capuchins are highly variable, ranging from affiliative to aggressive. In this paper I examine the affiliative relationships of all adult and subadult males residing in four social groups in Santa Rosa National Park, Costa Rica. Relationships among males in two study groups were neutral and tolerant, while in the remaining two groups males were highly affiliative. Male-male dyadic affiliative interactions were examined to determine which variables (group size, sex ratio, age relationship, relationship duration, and rank distance) influence the quality of male relationships within the study groups. Group size explained much of the variation, with males in small groups being more affiliative. However, the duration and history of the relationship among coresident males appears to be the most important variable in understanding male-male relationships within social groups.
