Abstract
Vocal communication is an essential aspect of primate social behaviour. The bearded capuchin Sapajus libidinosus is endemic to Brazil, and some studies have described specific vocalisation types for this species; however, there is still no complete description of its vocal repertoire. Thus, this study aimed to describe the vocal repertoire of a group of S. libidinosus living in theParque Nacional de Brasília, a protected area in the Cerrado area of Central Brazil. We carried out focal samplings and recording of vocalisations of members of an S. libidinosus troop in different behavioural contexts. The call analyses revealed 25 different types of vocalisations, and each call presented significant structural variation. We grouped these vocalisations according to the context of the emission or acoustic structure into the following categories: contact calls (contact note, infant babbling, trill, teeth- and lip-smacking, and sirena); foraging calls (chihui, grgr, and patinado); whistle series (food-associated, long-distance, and intergroup encounter); aggressive calls (aggressive contact note, ascending rapid staccato, cough cough, and pip); calls in response to aggression (scream, squeal, and pulsed scream), sexual display calls (chuck and raspy oestrous call), and stress-related calls (alarm call/bark, hiccup, hip, double hip, and wah wah). S. libidinosus presented a very rich vocal repertoire, revealing a pattern consistent with the repertoire of other capuchin monkey species. This is the first comprehensive description of the S. libidinosus vocal repertoire and highlights the complexity of neotropical primate communication.
期刊介绍:
Recognizing that research in human biology must be founded on a comparative knowledge of our closest relatives, this journal is the natural scientist''s ideal means of access to the best of current primate research. ''Folia Primatologica'' covers fields as diverse as molecular biology and social behaviour, and features articles on ecology, conservation, palaeontology, systematics and functional anatomy. In-depth articles and invited reviews are contributed by the world’s leading primatologists. In addition, special issues provide rapid peer-reviewed publication of conference proceedings. ''Folia Primatologica'' is one of the top-rated primatology publications and is acknowledged worldwide as a high-impact core journal for primatologists, zoologists and anthropologists.
