Abstract:
Although vocal sharing is widespread at several phylogenetic levels, few descriptions concerned primates. The present study involved the dynamics of vocal structures and social organization in a captive group of Campbell’s monkeys (Cercopithecus campbelli campbelli) at 3-year periods, using precise sound recording and comparison. The authors focused on combined harmonic 6 calls, often involved in vocal exchanges and associated with approaches. Each female produced 1 to 4 variants, shared, or not, between individuals. Changes appeared between years in the form of disappearance, appearance, or transformation of variants. There was a decrease in the global degree of sharing over the years. Greater changes were observed after social disturbance. Sharing would be more important in disturbed than stable groups to advertise bonds.
