Robbing and bartering (RB) is a behavioral practice anecdotally reported in free-ranging commensal macaques. It usually occurs in two steps: after taking inedible objects (e.g., glasses) from humans, the macaques appear to use them as tokens, returning them to humans in exchange for food. While extensively studied in captivity, our research is the first to investigate the object/food exchange between humans and primates in a natural setting. During a 4-month study in 2010, we used both focal… 
Cohort dominance rank and “robbing and bartering” among subadult male long-tailed macaques at Uluwatu, Bali
Dominance rank was strongly positively correlated with robbery efficiency in Riting, but not Celagi, meaning that more dominant Riting subadult males exhibited fewer overall robbery attempts per successful robbery.
Social influence on the expression of robbing and bartering behaviours in Balinese long-tailed macaques
The results support the cultural nature of the RB practice in the Uluwatu macaques and find that the synchronized expression of robbing and bartering could be explained by response facilitation.
Rates of human-macaque interactions affect grooming behavior among urban-dwelling rhesus macaques (Macaca mulatta).
The analysis shows that macaques engaged in shorter grooming bouts and were more vigilant while grooming in focal sessions during which they interacted with people more frequently, suggesting that humans directly affected grooming effort and vigilance behavior.
Comparative home range size and habitat selection in provisioned and non-provisioned long-tailed macaques (Macaca fascicularis) in Baluran National Park, East Java, Indonesia
Habitat selection, daily path length and home range size in long-tailed macaques in Baluran National Park, East Java, Indonesia, comparing a non-provisioned to a provisioned group is quantified.
Tourist Behavior Predicts Reactions of Macaques (Macaca fascicularis and M. nemestrina) at Sepilok Orang-utan Rehabilitation Centre, Sabah, Malaysia
Although improved education signs and staff supervision could further reduce visitor-directed aggression at Sepilok, these results are promising because they highlight the role that relatively simple policies (such as those that forbid provisioning by tourists) can play in reducing unwanted behavior by both humans and nonhuman primates at ecotourism locations.
Why intergroup variation matters for understanding behaviour
It is argued that IGV could plausibly explain inconsistent research findings across numerous topics of inquiry (experimental/behavioural studies on chimpanzees), and it is aimed to encourage researchers to explicitly consider IGV as an explanatory variable in future studies attempting to understand the socio-cognitive and evolutionary determinants of behaviour in group-living animals.
The Hand That Feeds the Monkey: Mutual Influence of Humans and Rhesus Macaques (Macaca mulatta) in the Context of Provisioning
It is found that provisioning influences macaque feeding ecology and habitat use, and that the behavior of the macaques themselves drives people to provide them with food subsidies, illustrating a complex web of interactions between the sympatric species.
Survey of Long-tailed macaque’s Behaviour in Mount Rinjani National Park, Lombok Timur
The results showed that the observed activities of Long-tailed macaque were feeding, sleeping, inactive, grooming, mating, moving, excretion, playing, making sound, and agonistic (fighting).
Interactions with humans impose time constraints on urban-dwelling rhesus macaques (Macaca mulatta)
It is found that macaques who interacted more frequently with people spent significantly less time resting and grooming, supporting the time constraints hypothesis, and arguing that these time constraints are likely caused by the unpredictability of human behaviour.
Use of an embedded fruit by Nicobar Long-tailed Macaque Macaca fascicularis umbrosus: II. Demographic influences on choices of coconuts Cocos nucifera and pattern of forays to palm plantations
The Nicobar Long-tailed Macaque Macaca fascicularis umbrosus, an insular sub-species uses coconuts Cocos nucifera, an embedded cultivar as a food resource and is speculated to have enhanced its dependence as a result of anthropogenic and environmental alterations.


Interactions between visitors and Formosan macaques (Macaca cyclopis) at Shou‐Shan Nature Park, Taiwan
If people refrain from feeding monkeys and destroying the city park's natural vegetation, monkeys can be used to educate public about nature conservation in an urban setting and provide evidence that food provisioning increased both the frequency and duration of aggression among Formosan macaques.
Disproportionate participation by age/sex classes in aggressive interactions between long‐tailed macaques (Macaca fascicularis) and human tourists at Padangtegal monkey forest, Bali, Indonesia
Variations in interaction patterns between macaques and tourists in Bali may have substantial implications for management issues and the potential for pathogen transmission.
Agonistic Interactions between Humans and Two Species of Monkeys (Rhesus Monkey Macaca mulatta and Hanuman Langur Semnopithecus entellus) in Shimla, Himachal Pradesh
The findings suggest that it is not the severity of attack by the rhesus monkeys, which is generally highlighted, but the overall dependence of this macaque on human resources is a matter of concern, and the strategies of conservation must be directed to minimize this dependence.
How Social Context, Token Value, and Time Course Affect Token Exchange in Capuchin Monkeys (Cebus apella)
Although numerous studies have examined token-directed behaviors in primates, few have done so in a social context despite the fact that most primate species live in complex groups. Here, we provided
Monkeys on the Edge: Ecology and Management of Long-Tailed Macaques and their Interface with Humans
The common monkey of southeast Asia: long-tailed macaque populations, ethnophoresy, and their occurrence in human environments, with implications for macaque-human interactions and for future research on long-tails macaques is published.
Temperament in Rhesus, Long‐Tailed, and Pigtailed Macaques Varies by Species and Sex
Comparisons of temperament between three closely related species of monkey suggest that adaptive species‐level social differences may be encoded in individual‐level temperaments, which are manifested even outside of a social context.
The macaque connection: Cooperation and conflict between humans and macaques
Across Asia, macaques, perhaps more than any other animal species, exemplify the multiple facets of synurbization and the conservation problems of commensal species.
Chimpanzees (Pan troglodytes) Flexibly Adjust Their Behaviour in Order to Maximize Payoffs, Not to Conform to Majorities
Investigating chimpanzees’ behavioural flexibility in two different conditions under which social animals have been predicted to abandon personal preferences and adopt alternative strategies found that chimpanzees did not abandon their behaviour in order to match the majority, but instead remained faithful to their first-learned strategy.
Cultures in chimpanzees
It is found that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted.
