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.

蓄须卷尾猴(头科:Sapajus libidinosus)的声乐功能:对理解新热带灵长类动物交流复杂性的影响。
声音交流是灵长类动物社会行为的一个重要方面。有胡须的卷尾猴Sapajus libidinosus是巴西特有的,一些研究已经描述了这个物种的特定发声类型;然而,至今仍没有对其声乐曲目的完整描述。因此,本研究旨在描述生活在巴西中部塞拉多地区国家公园Brasília保护区的一群S. libidinosus的声乐曲目。我们在不同的行为环境下对力比多沙鼠群体成员的发声进行了集中采样和记录。鸣叫分析揭示了25种不同的鸣叫类型,每种鸣叫都有显著的结构变化。我们根据发出声音的背景或声学结构将这些发声分为以下几类:接触叫声(接触音符、婴儿咿呀学语、颤音、牙齿和嘴唇的咂嘴声和sirena);觅食的叫声(赤晖、grgr和patinado);口哨系列(食物相关、远距离、群体间相遇);好斗的叫声(好斗的接触音,上升的快速断奏,咳嗽,咳嗽和pip);这些叫声是对攻击性的回应(尖叫、尖叫和脉冲式尖叫),性展示叫声(咔嗒声和刺耳的发情叫声),以及与压力有关的叫声(警报叫声/吠叫、打嗝、臀部、双臀和哇哇声)。S. libidinosus表现出非常丰富的声乐曲目,揭示了与其他卷尾猴物种的曲目一致的模式。这是第一次对S. libidinosus发声的全面描述,并突出了新热带灵长类动物交流的复杂性。
