     Conducting introductions of unfamiliar pairs of primates is a cornerstone of many behavioral management programs. However, these introductions may put unnecessary stress on the animals and require a good deal of personnel time, and that resource is wasted if the pair does not successfully complete the introduction process. Greater efficiency could be achieved if it was possible to better predict the outcome of introductions. A retrospective analysis was performed of behavioral data collected while subjects were individually housed, to determine if any behaviors were associated with the success of subsequent social pairings. Subjects included 34 adult rhesus macaques, six males and 28 females, all with similar mother-reared histories. Of the seventeen pairs introduced, 11 were successful and six were disbanded due to behavioral incompatibility. Behavioral data were coded using instantaneous sampling with a 15-second intersample interval via videotape for a total of 85 hours. Data were collapsed into seven categories for analysis: manipulate object, eat, inactive, locomote, self-directed, social, and abnormal. A between-subjects multivariate analysis of variance [a=0.05] indicated that there were no significant differences in the subjects that became a part of successful pairs, when compared to those subjects whose pairs were later disbanded. These findings suggest that general behavioral characteristics while subjects are housed alone do not predict the outcome of later social introductions.
