Some populations of capuchins are reported to use tools to solve foraging problems in the wild. In most cases, this involves the act of pounding and digging. The use of probing tools by wild capuchins is considerably less common. Here we report on the results of an experimental field study conducted in southern Brazil designed to examine the ability of wild black‐horned capuchins (Sapajus nigritus) to use a wooden dowel as a lever or a probe to obtain an embedded food reward. A group of eight… 

A robust tool kit: First report of tool use in captive crested capuchin monkeys (Sapajus robustus)

While crested capuchins have never been reported to use tools in the wild, the findings provide evidence for the species' capacity and propensity for tool use, highlighting the urgent need for research on this understudied, endangered primate.

Habitual stone-tool-aided extractive foraging in white-faced capuchins, Cebus capucinus

A population of white-faced capuchins in Coiba National Park, Panama who habitually rely on hammerstone and anvil tool use to access structurally protected food items in coastal areas including Terminalia catappa seeds, hermit crabs, marine snails, terrestrial crabs, and other items offers unique opportunities to explore the ecological drivers and evolutionary underpinnings of stone tool use.

The effects of tradition on problem solving by two wild populations of bearded capuchin monkeys in a probing task

It is suggested that behavioural traditions affect the ways non-human primates solve novel foraging problems using tools in the way that cultural knowledge may influence problem solving in wild populations of chimpanzees.

Development of tool-use behavior in a social context

Overall, infants and juveniles sustain a high level of interest in nuts and stones long before they can efficiently crack, and it is suggested that this interest is maintained with the help of tradition.

How Different Are Robust and Gracile Capuchin Monkeys? An Argument for the Use of Sapajus and Cebus

Morphological data support the division of capuchin monkeys into two genera, Sapajus Kerr, 1792, for robust capuchins and Cebus Erxleben, 1777, for gracilecapuchins, based on a review of extensive morphological, genetic, behavioral, ecological, and biogeographic evidence.

Wild Bearded Capuchins Process Cashew Nuts Without Contacting Caustic Compounds

It is described, for the first time, how a population of bearded capuchin monkeys (Sapajus libidinosus) accesses the nutritious kernel of cashew nuts avoiding the caustic chemicals protecting it.

The Ecology of Trunk-To-Trunk Leaping in Saguinus fuscicollis: Implications for Understanding Locomotor Diversity in Callitrichines

Across callitrichine taxa, it appears that ecological distinctions in diet, patterns of habitat utilization, and predator avoidance strategies have played an important role in understanding the frequency and context of trunk-to-trunk leaping behavior.

The Ontogeny of Prehensile‐Tail Use in Cebus capucinus and Alouatta palliata

Despite differences in tail anatomy in Cebus and Alouatta, prehensile‐tail use was observed to follow an increasing trajectory from infancy, peaking during juvenescence, and then decreasing in older juveniles and adults, and in both species, it appeared that adult patterns of prehensic tail use reflected the demands placed on young juveniles.

Competition during sugarcane crop raiding by blond capuchin monkeys (Sapajus flavius)

The pattern found indicates that consumption of a staple FBF does not directly translate into decreased competition and increased stability of social groups in forest fragments, as predicted by primate fallback foraging models.

Introduction to Special Issue on Capuchin Evolution: Comparing Behavior, Morphology, and Genetics across Species

A major goal of the special issue is to develop a strong evolutionary framework from which to assess capuchin behavior, ecology, and biology, including a clearer understanding of capuchin taxonomy.

Wild capuchins (cebus capucinus) fail to use tools

The results indicate that the capuchins did not use a tool to solve this novel foraging problem and did not attempt to touch or pick up the dowels.

Experimental field study of hand preference in wild black-horned (Cebus nigritus) and white-faced (Cebus capucinus) capuchins: evidence for individual and species differences

Support is provided for individual- and population-level handedness in wild capuchin monkeys in Brazil and Costa Rica during three visually-guided tasks.

The enhanced tool‐kit of two groups of wild bearded capuchin monkeys in the Caatinga: tool making, associative use, and secondary tools

On three occasions, the monkeys used smaller stones to loosen bigger quartz pebbles embedded in conglomerate rock, which were subsequently used as tools, which could be considered the first reports of secondary tool use by wild capuchin monkeys.

The results indicate that free-ranging capuchins do not exhibit the range of tool-using behavior demonstrated by their captive counterparts, and this may be the result of differential motivational responses to objects, arboreal lifestyle, absence of adequate tool material, and/or absence of food resources that require extraction involving tool-use.

Choosing and using tools: capuchins (Cebus apella) use a different metric than tamarins (Saguinus oedipus).

Capuchins discovered affordances of canes through exploratory actions with these objects, whereas tamarins did not, and ecological theory predicts these differences on the basis of species-typical manipulative activity, and it provides a useful approach for the study of species differences in tool-using behavior.

Spontaneous Tool Use by Wild Capuchin Monkeys (Cebus libidinosus) in the Cerrado

It is proposed that the probability of the emergence of the use of pounding stones as tools may be dependent on the ecological variables that influence the degree of terrestriality and extractive foraging and the complex interaction of these factors.

Lack of comprehension of cause-effect relations in tool-using capuchin monkeys (Cebus apella).

Four tufted capuchin monkeys, successful in a tool task in which they used a stick to push a reward out of a tube, were tested in a similar task, with a tube with a hole and a small trap, indicating that they did not take into account the effects of their actions on the reward.

First record of tool use by wild populations of the yellow‐breasted capuchin monkey (Cebus xanthosternos) and new records for the bearded capuchin (Cebus libidinosus)

Data is reported for the first time on tool use—stones as hammer and anvils to open nuts—in wild C. xanthosternos and a description of new tool using sites for C. libidinosus.

Wild capuchin monkeys (Cebus libidinosus) use anvils and stone pounding tools

An exploratory investigation in an area where nut‐cracking by wild capuchin monkeys is common knowledge among local residents finds physical evidence that monkeys cracked nuts on rock outcrops, boulders, and logs (collectively termed anvils).

Seasonal variation in use of time and space by the wedge-capped capuchin monkey, Cebus olivaceus : implications for foraging theory

The relationship between the foraging behavior of a group of wedge-capped capuchin monkeys Cebus olivaceus and the abundance and spatial distribution of resources, was examined in a highly seasonal gallery forest in central Venezuela during 14 months to evaluate the behavioral mechanisms regulating group foraging.
