Abstract The Parque Nacional de Brasilia, in Brazil, is visited daily by hundreds of people, because of its relative proximity to the city of Brasilia and the presence of natural swimming pools, trials and picnic areas. Capuchin monkeys habitually feed on the food that visitors give them, take food from the garbage and steal it from the visitors.

AbstractReports on use of stones as hammers and anvils to open hard nuts by wild capuchin monkeys are scarce and limited toCebus libidinosus. Here, we report for the first time data on tool use—stones as hammer and anvils to open nuts—in wildC. xanthosternosand a description of new tool using sites forC. libidinosus.

Chimpanzees have been the traditional referential models for investigating human evolution and stone tool use by hominins. We enlarge this comparative scenario by describing normative use of hammer stones and anvils in two wild groups of bearded capuchin monkeys (Cebus libidinosus) over one year.

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2011
The genotoxicity of two nitroimidazole derivatives, ornidazole (ONZ) and metronidazole (MTZ) in the peripheral blood lymphocytes of Cebus libidinosus (CLI) (Primates, Cebidae) was assessed. Endpoints measured included sister chromatid exchange (SCE) frequency, cell proliferation kinetics (CPK), replication index (RI), mitotic index (MI), and damage ...

AbstractWe investigated responses toward novel foods and novel objects by wild capuchins that routinely exploit visitors' foods in Brasília National Park. Given the capuchins' daily exposure to human foods and objects, we expected them to be more explorative toward novel foods and objects compared to capuchins that are not habituated to visitors ...

Wild bearded capuchins (Cebus libidinosus, quadrupedal, medium-sized monkeys) crack nuts using large stones. We examined the kinematics and energetics of the nut-cracking action of two adult males and two adult females. From a bipedal stance, the monkeys raised a heavy hammer stone (1.46 kg and 1.32 kg, from 33% to 77% of their body weight) to an ...

Do wild bearded capuchin monkeys (Cebus libidinosus) select anvils and habitat when use stone tools?
2011In Fazenda Boa Vista (Piauí, Brazil) wild bearded capuchins habitually use hammer stones and anvils to access the nutritious endosperm of encased fruit. Capuchins select hammers on the basis of material and weight, and occasionally to crack nuts they transport a stone hammer to an anvil.
