Several captive chimpanzees and bonobos have learned to use symbols and to comprehend syntax. Thus, compared with other nonhumans, these animals appear to have unusual cognitive powers that can be recruited for communicative behavior. This raises the possibility that wild chimpanzee vocal communication is more complex than heretofore demonstrated. To examine this possibility, I investigated whether wild chimpanzee vocal exchanges exhibit uniquely human conversational attributes. The results…

Youngsters do not pay attention to conversational rules: is this so for nonhuman primates?
These observations of Campbell's monkeys' spontaneous vocal utterances revealed that juveniles broke the turn-taking rule more often than did experienced adults, and parallels between human conversations and nonhuman primate vocal exchanges are strengthened.
Function of loud calls in wild bonobos.
It is concluded that bonobo females and males loud calls can function in inter-party communication to call others to large food patches and, unlike chimpanzees, are less important in male cooperative aggression.
Social bonding drives vocal exchanges in Bonobos
The results show that great apes spontaneously display primitive conversation rules guided by social bonds, which fills a significant gap in knowledge of vocal communication within the primate phylogeny and highlights the universal feature of social influence in vocal interactions.
The Chimpanzee Has No Clothes
An examination of four aspects of chimpanzee society that are prominent in discussions of human evolution—bipedal posture, tool use, cooperative hunting, and culture—indicates that other animals, even nonprimates, engage in analogous behaviors.
Social Basis of Vocal Interactions in Western Lowland Gorillas (Gorilla g. gorilla)
The results show that some apes use rule-governed call exchanges and that these socially guided vocal interactions are more widespread than previously believed.
Breaking conversational rules matters to captive gorillas: A playback experiment
The presence of proto-conversational rules in a captive gorilla group is experimentally investigated, using a violation-of-expectation paradigm, to support the growing number of studies highlighting the importance of vocal turn-taking in animals and a possible sociogenesis of this ability.
A pilot study of calling patterns and vocal turn-taking in wild bonobos Pan paniscus
Highlights This pilot study shows that wild bonobos display the fundamental temporal rules of vocal turn-taking Occurrences of calling patterns are in line with the unique observation collected from
On the state of nature and social life: thinking about humans and chimpanzees
This text proposes reflecting on the degrees of autonomy of social and cultural phenomena in relation to chimpanzee and human evolutionary predisposition to social life and to symbolic production as well as on the adaptive and non-adaptive aspects of these phenomena.

It is argued that language evolved from manual gestures, gradually incorporating vocal elements, and may be traced through changes in the function of Broca's area, the code for both the production of manual reaching movements and the perception of the same movements performed by others.
Nonlinear acoustics in pant hoots of common chimpanzees (Pan troglodytes): Frequency jumps, subharmonics, biphonation, and deterministic chaos
Results show that nonlinear phenomena are routinely present in chimpanzee pant hoots, and help lay the foundation for investigating the function of such events.


Behavioral mechanisms underlying vocal communication in nonhuman primates
In the wild, nonhuman primate vocalizations signal the presence of different predators, provide information about the group’s location and movement, facilitate friendly interactions, and lead to
Contexts and social correlates of long-distance calling by male chimpanzees
Abstract Abstract. Chimpanzees, Pan troglodytes , live in unstable social groups, whose members associate in temporary parties of varying size and composition. Male chimpanzees utter a long-distance
Rank differences in the production of vocalizations by wild chimpanzees as a function of social context
Rank differences in the production of vocalizations by wild, semihabituated, unprovisioned chimpanzees were investigated during a 10‐month study in the Kibale Forest, Uganda, suggesting that the provisioning area at Gombe was comparable to a natural socioecological context occurring at large fruiting trees.

Recordings and behavioral observations of wild chimpanzees were made over a 2‐year period in the Kibale National Park, Uganda to investigate patterns of acoustic variability in long‐distance calls, and it is suggested that younger males may pant hoot with specific adult males preferentially and that this may affect the development of their pant hoots acoustic morphologies.
Temporal and Acoustic Flexibility in Vocal Exchanges of Coo Calls in Japanese Macaques (Macaca fuscata)
A central issue in the study of primate vocalizations concerns the extent of control over vocal production, and failure to find evidence of learning is somewhat surprising, given the influence of learning on other behaviors.
Symbolic communication in wild chimpanzees?
Emergence of symbol-like communication in wild chimpanzees seems mainly dependent on a low visibility environment, a high predation pressure and a large group of males.
Temporal and Structural Analysis of Affiliative Vocal Exchanges in Squirrel Monkeys (Saimiri Sciureus)
Affiliative, aggressive, and vocal behaviors were observed in a group of five adult female squirrel monkeys. Affiliative partner preferences were correlated with use of the chuck vocalization.
Range use of the forest chimpanzees of Kibale: Implications for the understanding of chimpanzee social organization
It is concluded that the scenario in which females have smaller core areas within the defended home range of the males is most strongly supported by the range use patterns observed in Kibale chimpanzees.
The meaning and function of grunt variants in baboons
The results indicate that baboon grunts can function in rudimentary referential fashion, but that the context in which grunts are produced and the social identity of callers can also affect recipients' responses.
