     Three different groups of chimpanzees were formed and monitored through 41 introduction and post-introduction data-collection sessions. One male chimpanzee and seven female chimpanzees were involved in the formation of these groups. Analyses of 28.6 hours of behavioral data revealed significant differences in chimpanzee behavior during introduction phases versus post-introduction phases. Affiliative behavior (excluding grooming) (U = 62.5, p = .000), aggressive behavior (both noncontact, U = 155.0, p = .001, and contact, U = 88.0, p = .008)), submissive behavior (U = 80.5, p = .000) and sexual behavior (U = 149.5, p = .008) were all found to occur at a higher frequency (rate per minute) during introductions. Stress behavior, grooming behavior, dominance behavior and abnormal behavior were not significantly different between the two phases. Both groups of chimpanzees, one of four adult females and the other of one adult male and three adult females, were successfully formed, though one group required several separations and reintroductions. As facilities work towards building larger, more complex groups of chimpanzees, it is important to collect and share information about the behavior of chimpanzees during and after socializations as well as to investigate possible early predictors for success.
