“…Sugiura (1998) conducted a playback experiment that took advantage of a macaque's tendency to respond with a coo when it hears one emitted by a member of their group. Sugiura (1998) found that macaques modified their contact call to match acoustic features of the played back contact call. Miller et al (2004) show that killer whales engage in exchanges of the same signal, and Miller (2002) shows by comparing the amount of energy in high vs low frequencies in such a known signal, a killer whale not only should be able to tell where another whale is, but also whether it is swimming towards or away.…”

“…Mundinger (1970) in the first description of vocal convergence in bird calls suggests "Taken as a whole the data provide support for the hypothesis that avian vocal imitation is sometimes employed for recognizing and maintaining contact with other members of the species." (p 482) The coo call of Japanese macaques is thought to function to maintain contact (Sugiura 1998). Tanaka et al (2006) compared coo calls from two groups of Japanese macaques, and found differences between the two groups that develop 6-7 months after birth.…”

The classic evidence for vocal production learning involves imitation of novel, often anthropogenic sounds. Among mammals, this has been reported for African elephants, harbor seals, and dolphins. A broader taxonomic distribution has been reported for vocal convergence, where the acoustic properties of calls from different individuals converge when they are housed together in captivity or form social bonds in the wild. This kind of vocal convergence has been demonstrated for animals as diverse as songbirds, parakeets, bats, elephants, cetaceans, and primates. For most of these species, call convergence is thought to reflect a group-distinctive identifier, with shared calls reflecting and strengthening social bonds. Pooling data on vocal imitation and vocal convergence suggests a wider taxonomic distribution of vocal production learning among mammals than generally appreciated. The wide taxonomic distribution of this evidence for vocal production learning suggests that perhaps more of the neural underpinnings for vocal production learning are in place in mammals than is usually imagined. One ubiquitous function for vocal production learning that is starting to receive attention involves modifying signals to improve communication in a noisy channel.

“…Another phenomenon found in humans is acoustic convergence during conversations, an effect that is particularly common among closely bonded individuals. In non-human primates, similar effects appear to exist, both long-term (months and years) [15,25] and short-term, as shown by patterns of coo call exchanges in Japanese macaques (Macaca fuscata) [14]. In our study, females produced calls that were more similar to calls they responded than to calls they did not respond to, suggesting that females were not just similarly motivated but adjusted the acoustic structure of their calls in relation to specific social motivations.…”

Convergence and divergence in Diana monkey vocalizations

International audienceIndividually distinct vocalizations are widespread among social animals, presumably caused by variation in vocal tract anatomy. A less-explored source of individual variation is due to learned movement patterns of the vocal tract, which can lead to vocal convergence or divergence in social groups. We studied patterns of acoustic similarity in a social call produced by 14 female Diana monkeys (Cercopithecus diana) in two free-ranging groups. Calls showed variability in fundamental frequency contours owing to individual identity and external context. Vocal divergence increased significantly between females during poor visibility and tended to increase in the presence of neighbours. In contrast, vocal convergence increased significantly between females during vocal interactions, because females matched the frequency contour of their own call with another female's preceding call. Our findings demonstrate that these primates have some control over the acoustic fine structure of their most important social vocalization. Vocal convergence and divergence are two opposing processes that enable callers to ensure spatial proximity and social cohesion with other group members

“…Here, I found that animals were more likely than expected to produce a signature whistle in the five seconds following their partner's signature whistle. Vocal exchanges where a receiver responds to a produced signal by replying with its own signal have been reported in many animals ranging from primates (Sugiura, 1993(Sugiura, , 1998Miller et al, 2009) to song birds (Krebs et al, 1981) to odontocetes . Thus, the observed increase in probability of a signature whistle is consistent with the hypothesis that animals are responding to each other's signature whistles by producing their own signature whistles.…”

The choreography of belonging : toothed whale spatial cohesion and acoustic communication

To maintain the benefits of group membership, social animals need mechanisms to stay together and reunite if separated. This thesis explores the acoustic signals that dolphins use to overcome this challenge and mediate their complex relationships in a dynamic 3D environment. Bottlenose dolphins are the most extensively studied toothed whale, but research on acoustic behavior has been limited by an inability to identify the vocalizing individual or measure inter-animal distances in the wild. This thesis resolves these problems by simultaneously deploying acoustic tags on closely-associated pairs of known animals. These first reported deployments of acoustic tags on dolphins allowed me to characterize temporal patterns of vocal behavior on an individual level, uncovering large variation in vocal rates and inter-call waiting time between animals. Looking more specifically at signature whistles, a type of call often linked to cohesion, I found that when one animal produced its own signature whistle, its partner was more likely to respond with its own whistle. To better evaluate potential cohesion functions for signature whistles, I then modeled the probability of an animal producing a signature whistle at different times during a temporary separation and reunion from its partner. These data suggest that dolphins use signature whistles to signal a motivation to reunite and to confirm identity prior to rejoining their partner. To examine how cohesion is maintained during separations that do not include whistles, I then investigated whether dolphins could keep track of their partners by passively listening to conspecific echolocation clicks. Using a multi-pronged approach, I demonstrated that the passive detection range of echolocation clicks overlaps with the typical separation ranges of Sarasota mother-calf pairs and that the amount of time since an animal was last able to detect a click from its partner helped explain its probability of producing a signature whistle. Finally, this thesis developed a portable stereo camera system to study cohesion in situations where tagging is not possible. Integrating a GPS receiver, an attitude sensor and 3D stereo photogrammetry, the system rapidly positions multiple animals, grounding behavioral observations in quantitative metrics and characterizing fine-scale changes that might otherwise be missed.
