“…Despite the aforementioned differences, the overall form of food transfer behavior was similar in wild and reintroduced animals: immatures solicit with conspicuous signals and behavior and receive most transfers, and transfers of naturally occurring foods were biased toward require prey and some fruits. Adults occasionally offered food with a food-transfer call, which seems to be limited to this context [see also Boinski et al, 1994], and/or by sitting with an outstretched forearm [Brown & Mack, 1978;Hoage, 1982]. The form of the call is not stereotyped nor was its occurrence as common as previously suggested for captive tamarins [Brown & Mack, 1978;Hoage, 1982;Rapaport, 1997].…”

“…Two observers recorded vocalizations and behavioral context [Boinski et al, 1994]. "Observer 1" recorded all vocalizations of the focal animal on one channel of a Marantz PMD 430 cassette recorder while narrating into a lapel microphone connected to a second channel the time of day, the behavior of the focal animal, its location in reference to the group, and the general activity of the group (e.g., foraging, traveling, resting, etc.)…”

“…Relationships between vocal signalling and social cohesion, and between certain vocal signals and specific social interactions, have been documented in detail for many non-human primate species with complex social groups (e.g. chacma baboons, Papio hamadryas ursinus [25,26]; white-faced capuchins, Cebus capucinus [27]; golden lion tamarins, Leontopithecus rosalia [28]; (reviews in [17,29]).…”

The Paridae family (chickadees, tits and titmice) is an interesting avian group in that species vary in important aspects of their social structure and many species have large and complex vocal repertoires. For this reason, parids represent an important set of species for testing the social complexity hypothesis for vocal communication—the notion that as groups increase in social complexity, there is a need for increased vocal complexity. Here, we describe the hypothesis and some of the early evidence that supported the hypothesis. Next, we review literature on social complexity and on vocal complexity in parids, and describe some of the studies that have made explicit tests of the social complexity hypothesis in one parid—Carolina chickadees, Poecile carolinensis. We conclude with a discussion, primarily from a parid perspective, of the benefits and costs of grouping and of physiological factors that might mediate the relationship between social complexity and changes in signalling behaviour.

“…Many primate species rely on vocal communication to mediate social interactions (Epple, 1968; Seyfarth et al, 1980; Boinski, 1993; Boinski et al, 1994; Clark and Wrangham, 1994; Vitale et al, 2003; Arnold and Zuberbühler, 2006), and the complexity of their call repertoires appears to be a function of adaptive pressure (Stephan and Zuberbühler, 2008). In spite of the importance of primate vocal communication, our understanding of its neural underpinnings is still quite limited.…”

Primates often rely on vocal communication to mediate social interactions. Although much is known about the acoustic structure of primate vocalizations and the social context in which they are usually uttered, our knowledge about the neocortical control of audio–vocal interactions in primates is still incipient, being mostly derived from lesion studies in squirrel monkeys and macaques. To map the neocortical areas related to vocal control in a New World primate species, the common marmoset, we employed a method previously used with success in other vertebrate species: Analysis of the expression of the immediate early gene Egr-1 in freely behaving animals. The neocortical distribution of Egr-1 immunoreactive cells in three marmosets that were exposed to the playback of conspecific vocalizations and vocalized spontaneously (H/V group) was compared to data from three other marmosets that also heard the playback but did not vocalize (H/n group). The anterior cingulate cortex, the dorsomedial prefrontal cortex and the ventrolateral prefrontal cortex presented a higher number of Egr-1 immunoreactive cells in the H/V group than in H/n animals. Our results provide direct evidence that the ventrolateral prefrontal cortex, the region that comprises Broca's area in humans and has been associated with auditory processing of species-specific vocalizations and orofacial control in macaques, is engaged during vocal output in marmosets. Altogether, our results support the notion that the network of neocortical areas related to vocal communication in marmosets is quite similar to that of Old world primates. The vocal production role played by these areas and their importance for the evolution of speech in primates are discussed.
