All known chimpanzee populations have been observed to hunt small mammals for meat. Detailed observations have shown, however, that hunting strategies differ considerably between populations, with some merely collecting prey that happens to pass by while others hunt in coordinated groups to chase fast-moving prey. Of all known populations, Taï chimpanzees exhibit the highest level of cooperation when hunting. Some of the group hunting roles require elaborate coordination with other hunters as… 

Reward of labor coordination and hunting success in wild chimpanzees

It is concluded that chimpanzee hunting is cooperative, likely facilitated by behavioral and neuroendocrine mechanisms of coordination and reward, and meat sharing behavior and oxytocin in wild chimpanzees is examined, elucidating the mechanism facilitating cooperation.

Hunting Activity Among Naturalistically Housed Chimpanzees (Pan troglodytes) at the Fundació Mona (Girona, Spain). Predation, Occasional Consumption and Strategies in Rehabilitated Animals

It is confirmed that naturalistic environments allow chimpanzees to enhance species-typical behavioral patterns in a naturalistic environment without learning it in the wild.

Vocal signals facilitate cooperative hunting in wild chimpanzees

The results indicate that the coevolutionary relationship between vocal communication and group-level cooperation is not unique to humans in the ape lineage and is likely to have been present in the authors' last common ancestor with chimpanzees.

The meat-scrap hypothesis: small quantities of meat may promote cooperative hunting in wild chimpanzees (Pan troglodytes)

A mathematical model is described demonstrating that group hunting may evolve when individuals can obtain micronutrients more frequently by hunting in groups than by hunting solitarily, provided that group size is below a certain threshold.

Prey preferences of the chimpanzee (Pan troglodytes)

Prey preference information from chimpanzee research can assist conservation management programs by identifying key prey species to manage, as well as contribute to a better understanding of the evolution of human hunting behavior.

Variation in hunting behaviour in neighbouring chimpanzee communities in the Budongo forest, Uganda

The two most likely and probably interrelated explanations for the observed intergroup variation in chimpanzee hunting behaviour are discussed, long-term disruption of complex group-level behaviour due to human presence and possible socially transmitted differences in prey preferences.

Hunting of mammals by central chimpanzees (Pan troglodytes troglodytes) in the Loango National Park, Gabon

The first direct observations of hunting behaviour by individuals of the newly habituated Rekambo community in the Loango National Park, Gabon are provided, with a hunting frequency of 2.65 hunts per month, which explains seasonal variation in hunting behaviour in several populations of eastern chimpanzees.

How chimpanzees cooperate in a competitive world

The results suggest that the roots of human cooperation are shared with other primates, and shared mechanisms across the primates to mitigate competition for the sake of cooperation are suggested.

Longitudinal changes in the targets of chimpanzee (Pan troglodytes) hunts at Mahale Mountains National Park: how and why did they begin to intensively hunt red colobus (Piliocolobus rufomitratus) in the 1980s?

The hunting activities of chimpanzees (Pan troglodytes) at Mahale Mountains National Park exhibited a significant change over a 46-year observation period, shifting from sporadic hunting for small

Forest chimpanzees have a more specialized prey image, intentionally search for more adult prey, and hunt in larger groups and with a more elaborate cooperative level than savanna-woodlands chimpanzees, and tend to share meat more actively and more frequently.

It is concluded that the large size of the Ngogo community contributes to their extraordinary hunting success, and demographic differences between groups are likely to contribute to other patterns of interpopulation variation in chimpanzee predation.

Cooperative hunting in wild chimpanzees

Abstract Abstract. A model for the evolution of cooperation shows that two conditions are necessary for cooperation to be stable: a hunting success rate that is low for single hunters and increases

Chimpanzees-red colobus monkeys: a predator-prey system

A scheme is proposed that could account for the evolution between the two species from the aggressive colobus and fearful chimpanzees in Gombe to the more wary colobuses and confident chimpanzees in the Tai forest.

Patterns of predation by chimpanzees on red colobus monkeys in Gombe National Park, 1982-1991.

Predatory patterns in wild chimpanzees are important evidence in the continuing debate about the role of hunting in the behavior of early hominids, and hunting showed a strong "binge" tendency from 1982 to 1991.

Individually identified lions (Panthera leo) were observed on the open, semi-arid plains in Namibia to assess cooperation and individual variation in hunting tactics and the role of cooperative hunting is discussed.

Altruistic cooperation during foraging by the Ache, and the evolved human predisposition to cooperate

Data show that Ache men and women spend about 10% of all foraging time engaged in altruistic cooperation on average, and that on some days they may spend more than 50% of their forager time in such activities.

Factors influencing the hunting success of an African wild dog pack

Two ways in which wild dogs may benefit from communal hunting are suggested, which increased the range of prey species available to the pack and reduced interspecific competition from spotted hyaenas, Crocuta crocuta, through improved defence of carcasses.

Foraging behaviour and hunting success of lions in Queen Elizabeth National Park, Uganda

Cover, prey availability and prey body size appeared to be the major causes of variation in lion foraging behaviour between study sites, and lions foraged most often during moonless nights, when their hunting success was greatest.
