Shortly after two groups of stumptail macaques were formed, their individual and social behavior was observed. Similar overall behavior of the two groups arose from different interaction patterns within the groups. Hierarchical stabilities and instabilities were related to selective affilliation patterns. The main instabilities were found at the top of the hierarchy of one group and in the middle of the other. The roots of later changes in group structure were displayed in individual association preferences.
