Diversity of nutcracking tool sites used bySapajus libidinosusin BrazilianCerrado

American Journal of Primatology, 2015
Cracking nuts with tools is a behavior documented in a small number of populations of tufted capuchins, mainly in semi‐aridCaatingaandCaatinga–Cerradotransitional environments of northeastern Brazil. Only one of these populations inhabits the less aridCerradoin Central Brazil, where environments are composed of a heterogeneous mosaic of fields ...

Bearded capuchin (Sapajus libidinosus) predation on a rock cavy (Kerodon rupestris) followed by prey sharing

Primates, 2021
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.

Optional tool use: The case of wild bearded capuchins (Sapajus libidinosus) cracking cashew nuts by biting or by using percussors

American Journal of Primatology, 2020
Tool use in humans can be optional, that is, the same person can use different tools or no tool to achieve a given goal. Strategies to reach the same goal may differ across individuals and cultures and at the intra‐individual level.

Validation of an Enzyme Immunoassay for Measuring Fecal Cortisol Metabolites of Bearded (Sapajus libidinosus) and Black (Sapajus nigritus) Capuchins

International Journal of Primatology, 2017
Fecal steroid analysis is a powerful noninvasive tool for behavioral endocrinology, but enzyme immunoassays (EIAs) require experimental validation before they are applied. We conducted a physiological validation of an in-house EIA measuring fecal cortisol metabolites (FCMs) by performing an adrenocorticotrophic hormone (ACTH) challenge, dexamethasone ...

Determination of baseline values for routine ophthalmic tests in bearded capuchin (Sapajus libidinosus)

Journal of Medical Primatology, 2018
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.

Hematological parameters of captive capuchin monkeys (Sapajus libidinosus and S. apella) illegally kept in homes in northeast Brazil

Neotropical Primates
This study presents the hematological parameters of captive capuchin monkeys (Sapajus libidinosus and S. apella) kept in homes in the state of Ceará, in Northeast Brazil. Morphometry measurements and blood samples were taken from 35 individuals illegally

Distinct perceptuomotor features of percussive tooling in humans (Homo sapiens) and wild bearded capuchin monkeys (Sapajus libidinosus).

Journal of Comparative Psychology, 2020
Adjustment of percussive movements to match the energetic requirements of the task serves as an index of skill in stone-knapping and nut-cracking. In this study, we compared strike-by-strike adjustment of percussive movements in expert bearded capuchin ...
