Female bearded capuchin monkeys (Sapajus libidinosus) use objects to solicit the sexual partner.
Journal of Comparative Psychology, 2017Female wild bearded capuchins (Sapajus libidinosus) living at Serra da Capivara National Park (SCNP) that use stone and stick tools during foraging occasionally toss or throw stones at the male during courtship. We report similar behaviors in a different population that uses stones as tools in foraging.

AbstractBackgroundEstablish baseline values for ophthalmic diagnostic tests inSapajus libidinosus.MethodsOphthalmic diagnostic tests, namely Schirmer tear test 1 (STT‐1), intraocular pressure (IOP), B‐mode ultrasound, culture of the bacterial conjunctival microbiota, and conjunctival exfoliative cytology, were performed in 15S.

We describe predation on an adult rodent rock cavy and sharing of the carcass by a group of male bearded capuchins. Despite many studies, such an interaction has never been observed in bearded capuchins. Rock cavies are large rodents weighing around 25% of the weight of an adult male bearded capuchin.

Food or threat? Wild capuchin monkeys (Sapajus libidinosus) as both predators and prey of snakes
Primates, 2017Snakes present a hazard to primates, both as active predators and by defensive envenomation. This risk might have been a selective pressure on the evolution of primate visual and cognitive systems, leading to several behavioral traits present in human and non-human primates, such as the ability to quickly learn to fear snakes.

The habitual use of tools by wild capuchin monkeys presents a unique opportunity to study the maintenance and transmission of traditions. Young capuchins spend several years interacting with nuts before cracking them efficiently with stone tools. Using a two-observer method, we quantified the magnitude of the social influences that sustain this long ...

Understanding the selective pressures that drove the evolution of bipedalism in the human lineage may help inform researchers about the locomotor mode(s) of pre-hominin ancestors. Several selective pressures have been hypothesized, including the need to carry food, tools, or infants. Bearded capuchin monkeys are an excellent primate in which to examine

Cashew nuts are very nutritious but so well defended by caustic chemicals that very few species eat them. We investigated how wild bearded capuchin monkeys (Sapajus libidinosus) living at Fazenda Boa Vista (FBV; Piauí, Brazil) process cashew nuts (Anacardiumspp.) to avoid the caustic chemicals contained in the seed mesocarp. We recorded the behavior of

There is evidence that wild animals are able to recall key locations and associate them with navigational routes. Studies in primate navigation suggest most species navigate through the route network system, using intersections among routes as locations of decision-making. Recent approaches presume that points of directional change may be key locations

ABSTRACTA free‐ranging capuchin monkey developed a synchronous biphasic pleural and peritoneal mesothelioma, a rare form of this tumor. Exophytic nodules were dispersed over the serosal surfaces, showing marked microscopical malignant features composed of both epithelioid and spindeloid neoplastic cells immunopositive for Pan‐Cytokeratin, Cytokeratin 5/

Diet and seed dispersal of bearded capuchin monkeys (Sapajus libidinosus) in Brasilia National Park
American Journal of PrimatologyAbstractThe dietary ecology of a species can provide information on habitat requirements, food resources, and trophic interactions, important to guide conservation efforts of wildlife populations in endangered habitats. In this study, we investigated the dietary ecology of bearded capuchin monkeys (Sapajus libidinosus) in Brasilia National Park, in the
