Social Status of Two Hybrids in a Wild Troop of Macaca Irus

Abstract

The organization and social behavior of a troop of Macaca irus containing 2 animals identified as hybrids with M. nemestrina, was studied for 4 months. During the latter 2 months, provisioning was used to permit intensive observation of agonistic episodes which were then analyzed to indicate the status hierarchy of the troop. The 2 hybrids were well integrated members of the troop with the male serving in the capacity of control male. Response patterns observed in the hybrids could not be differentiated from those of other troop members, but reproductive patterns were not observed in the hybrids.
