| Abstract | We investigated the potential use of call playback for surveying the elusive golden-backed uakari (Cacajao melanocephalus), a diurnal social primate that typically inhabits the relatively inaccessible black-water swamp forests of the upper Amazon (Igapó forest) during the wet season. Furthermore, our objective was to understand better the functions of vocalisations of these rare and threatened monkeys. We focussed on the 'tchó' call, a loud vocalisation that varies in temporal and frequency characteristics according to behavioural context and individual signaller (Bezerra et al. in Int J Primatol, 2010b). We investigated the vocal and behavioural responses of golden-backed uakaris from three Igapó areas to three different playback stimuli: own group calls (OGC); neighbouring group calls (NGC); and control (background noise). The call stimuli were used to simulate the unexpected presence of monkeys from the monkeys' own and neighbouring Igapó areas. Playback of OGC and NGC increased calling and altered behaviour in golden-backed uakaris, whereas no noticeable response occurred to the control stimuli. Furthermore, there was no evidence of habituation to the call stimuli and the natural behavioural pattern of the groups was not obviously affected. Hence, call playback seems to be a valuable tool for locating these elusive monkeys in river surveys. Most of the agonistic-related behaviour observed after NGC playback was also observed after OGC playback. As golden-backed uakaris are not territorial, the presence of strange conspecifics to the area may not necessarily represent a more threatening situation. Our methods and results may also be useful for surveys of other primate species living in the Igapó forest and in other habitat types. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
