The use of stones to crack open encapsulated fruit is widespread among wild bearded capuchin monkeys (Cebus libidinosus) inhabiting savanna‐like environments. Some populations in Serra da Capivara National Park (Piauí, Brazil), though, exhibit a seemingly broader toolkit, using wooden sticks as probes, and employing stone tools for a variety of purposes. Over the course of 701.5 hr of visual contact of two wild capuchin groups we recorded 677 tool use episodes. Five hundred and seventeen of… Expand
The manifold use of pounding stone tools by wild capuchin monkeys of Serra da Capivara National Park, Brazil
The use of pounding stone tools (PSTs) is a customary behaviour in several wild populations of capuchin monkeys; most of these monkeys use PSTs primarily to open hard palm nuts. Here, we describe theExpand
Stone tool use by adult wild bearded capuchin monkeys (Cebus libidinosus). Frequency, efficiency and tool selectivity.
TLDR
It is argued that the contrasting pattern of sex differences in capuchins compared with chimpanzees, in which females use tools more frequently and more skillfully than males, may have arisen from the degree of sexual dimorphism in body size of the two species, which is larger in capuchin monkeys than in chimpanzees. Expand
Adaptability in stone tool use by wild capuchin monkeys (Sapajus libidinosus)
TLDR
Evidence of adaptability in the use of stone tools by the capuchin monkey population of Serra Talhada provides an example of the complexity that these primates demonstrate in food processing. Expand
Sexual bias in probe tool manufacture and use by wild bearded capuchin monkeys
TLDR
Examination of data from a two-year research on the use of sticks as probes by two groups of wild capuchin monkeys (Sapajus libidinosus) in Serra da Capivara National Park, Brazil finds a strong male bias in the occurrence of probe tool use. Expand
Optional tool use: The case of wild bearded capuchins (Sapajus libidinosus) cracking cashew nuts by biting or by using percussors
TLDR
It is suggested that success at opening cashews with a tool 1–2 years earlier than they succeed at cracking more resistant palm nuts may support the monkeys' persistent efforts to crack palm nuts. Expand
Author ' s personal copy Stone tool use by adult wild bearded capuchin monkeys ( Cebus libidinosus ) . Frequency , ef fi ciency and tool selectivity
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 hammerExpand
Digging up food: excavation stone tool use by wild capuchin monkeys
TLDR
Both groups used tools while digging three main food resources: Thiloa glaucocarpa tubers, Ocotea sp roots, and trapdoor spiders, and the data do not support the fallback food hypothesis for the use of tools to access burrowed resources. Expand
Habitual stone-tool-aided extractive foraging in white-faced capuchins, Cebus capucinus
TLDR
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. Expand
Stone tool use in wild bearded capuchin monkeys, Cebus libidinosus. Is it a strategy to overcome food scarcity?
TLDR
To determine whether tool use varied in relation to food availability in bearded capuchin monkeys, anvil and stone hammer use was recorded in two sympatric wild groups, and climatic variables and availability of fruits, invertebrates and palm nuts were assessed. Expand
Stone tool use by wild capuchin monkeys (Sapajus libidinosus) at Serra das Confusões National Park, Brazil
Capuchin monkeys (Sapajus spp.) are proficient tool users, and the use of stone tools occurs in several populations, mostly to crack open encased foods. Two well-studied Brazilian populations ofExpand

Characteristics of hammer stones and anvils used by wild bearded capuchin monkeys (Cebus libidinosus) to crack open palm nuts.
TLDR
Wild capuchins provide a new reference point for interpreting early percussive stone tool use in hominins, and a point of comparison with chimpanzees cracking nuts. Expand
Wild capuchin monkeys (Cebus libidinosus) use anvils and stone pounding tools
TLDR
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). Expand
Wild capuchins (cebus capucinus) fail to use tools
TLDR
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. Expand
Semifree-ranging Tufted Capuchins (Cebus apella) Spontaneously Use Tools to Crack Open Nuts
TLDR
A role for observational learning is suggested, even if restricted to stimulus enhancement, in a group of semifree-ranging capuchins living in a reforested area (Tietê Ecological Park, São Paulo, Brazil). Expand
Capuchin Stone Tool Use in Caatinga Dry Forest
TLDR
Wild capuchin monkeys inhabiting dry forest were found to customarily use tools as part of their extractive foraging techniques, which consisted of twigs and sticks used to probe for insects and stones used for cracking and digging. Expand
Capuchin monkey tool use: Overview and implications
Nutcracking capuchins are mentioned in reports dating as far back as the sixteenth century, 1 , 2 as well as in Brazilian folklore. 3 However, it was barely a decade ago that primatologistsExpand
Social tradition and the use of tool‐composites by wild chimpanzees
TLDR
Use of more than one kind of tool for a single task, a tool‐composite, by wild chimpanzees (Pan troglydytes) demonstrates high intelligence and motor control which requires foresight, understanding of relations among tools and task, and behavioral coordination. Expand
Use of a tool-set by capuchin monkeys (Cebus apella)
TLDR
Capuchins' behavior was similar in form and function to behavior that has been reported for chimpanzees in analogous situations and is consistent with a hypothesis of cross-species continuity in the skillful use of tools by primates. Expand
