Male‐Male Greeting Behavior Observed in Chacma Baboons ( <scp> <i>Papio ursinus griseipes</i> </scp> ) in Gorongosa National Park, Mozambique

Strong similarities in signal use between the sample of chacma baboon greetings and published accounts of olive, hamadryas, and yellow baboon greetings were identified. Specifically, rates of physical contact, intense physical contact, and reciprocal use of facial expressions were similar to those of the other Papio species, excluding the Guinea baboon which exhibits more stereotyped and highly physical greetings. The proportion of observed chacma baboon greetings which were considered "incomplete" (i.e., exhibiting only facial signals, with no presenting or contact) however, was greater than in the other baboon species, highlighting a key difference that may reflect the lower level of male tolerance and weaker male relationships in chacma baboons compared to other baboon species.
