Reconiliation is an integral element in social relationships. The purpose of this naturalistic observational study was to determine whether green monkeys (Chlorocebus sabaeus) engae in reconciliatory behavior. Focal data were collected on a group of free-ranging green monkeys in the Barbados Wildlife Reserve. There were 7 adult females and 2 adult males in the group. To code affiliative behavior among the sample, an ethogram was developed which included the following behaviors: groom, play, proximity, lip-smacking, mount and nuzzle. The PC-MC (post conflict-matched control) method was useed to compare affiliative behaviors following a conflict to baseline periods. Since there were no instances of play, mount or nuzzle, no analyses were conducted on these three behaviors. Post-conflict proximity was significantly higher than baseline rates t(8)=2.53, p=.035 with a large effect size, Cohen's d=.84. Rates of grooming following a fight were significantly higher than rates at the baseline level t(8)=1.51, p=.17. Cohen's d=.50. Finally, lip-smacking following conflict was higher during times of no conflict t(8)=1.51, p=.17, Cohen's d=.50 These finding suggest that higher rates of affiliation represent reconciliation among the green monkeys.
