During 23 months we observed 110 inter-group interactions involving four groups of chacma baboons in the Okavango Delta, Botswana.

Males also chased members of the opposing group more when estrous females were present. When estrous females were absent, male displays were shorter in duration, involved fewer participants, were less intense, and were more likely to result in peaceful mingling between groups.
