However, intergroup interactions may occur when several groups drink from the same water hole. The total of all day ranges, or the home range, of this species 3,200 hectares. When intergroup conflicts do occur, females and young are more active than males. Males may only give loud warning calls. However, during the mating season males join females in antagonizing other groups.
Females tend to defend the resources in their home range against females in other groups.
In terms of intragroup relations, social organization is not well known. Dominance hierarchies are not apparent among patas monkey groups. However, it has been observed that a network of dyads with characteristically more than average affiliative behavior exists which indicates that some sort of pattern of social behavior is present. This is especially true of species with similiar age and sex, and perhaps among kin. Captive patas monkeys have confirmed these patterns.
