Chimpanzees (Pan troglodytes) prey on a variety of vertebrates, mostly on red colobus (Procolobus spp.) where the two species are sympatric. Variation across population occurs in hunting frequency and success, in whether hunting is cooperative, i.e., payoffs to individual hunters increase with group size, and in the extent to which hunters coordinate their actions in space and time, and in the impact of hunting on red colobus populations. Also, hunting frequency varies over time within… Expand
Influence of chimpanzee predation on the red colobus population at Ngogo, Kibale National Park, Uganda
TLDR
Test the hypothesis that chimpanzee hunting is sustainable, using demographic data collected on red colobus monkeys over a period of 3 years, as well as fecundity and mortality data from previous studies of this species, and applies matrix models and vortex analyses using a sensitivity analysis approach.

Hunting of mammals by central chimpanzees (Pan troglodytes troglodytes) in the Loango National Park, Gabon
TLDR
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. Expand
Hunting and Prey Switching by Chimpanzees (Pan troglodytes schweinfurthii) at Ngogo
TLDR
It is implied that the red colobus population is not recovering and the possibility that the chimpanzees are having a negative impact on the guereza population is raised. Expand
Diet of chimpanzees (Pan troglodytes schweinfurthii) at Ngogo, Kibale National Park, Uganda, 1. diet composition and diversity
TLDR
Data on diet composition and diversity for chimpanzees at Ngogo, in Kibale National Park, Uganda, collected over a 15‐year period support the argument that chimpanzees are ripe fruit specialists: Ngogo chimpanzees ate a broad, mostly fruit‐based diet, feeding time devoted to fruit varied positively with fruit availability, and diet diversity varied inversely with Fruit availability. Expand
Variation in hunting behaviour in neighbouring chimpanzee communities in the Budongo forest, Uganda
TLDR
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. Expand
Grouping Patterns and Competition Among Female Pan troglodytes schweinfurthii at Ngogo, Kibale National Park, Uganda
TLDR
Ngogo females maintained relatively high levels of gregariousness, but avoided detrimental feeding competition by preferentially associating with a small subset of other community females. Expand
Chimpanzee‐red colobus encounter rates show a red colobus population decline associated with predation by chimpanzees at Ngogo
TLDR
Data from 1998 to 2012 are presented on the rate of encounters between chimpanzees and red colobus that provide a chimpanzee‐centered estimate of red colOBus density, thus of predation opportunities, throughout the home range and corroborate Teelen's conclusion that chimpanzee predation on red Colobus during the 1990s and early 2000s was unsustainable.

Tool Use by Chimpanzees at Ngogo, Kibale National Park, Uganda

Chimpanzees make and use a wide variety of tools in the wild. The size and composition of their toolkits vary considerably among populations and at least to some extent within them. Chimpanzees atExpand
Scavenging by chimpanzees at Ngogo and the relevance of chimpanzee scavenging to early hominin behavioral ecology.
  • D. Watts

  • Journal of human evolution
  • 2008
TLDR
All known opportunities for scavenging encountered by chimpanzees at Ngogo, Kibale National Park, Uganda are documented, and all cases of scavenging are described, which apparently distinguishes chimpanzee foraging strategies from those of at least some Oldowan hominins. Expand
Diet of chimpanzees (Pan troglodytes schweinfurthii) at Ngogo, Kibale National Park, Uganda, 2. temporal variation and fallback foods
TLDR
Investigation of temporal dietary variation and use of fallback foods by chimpanzees at Ngogo, Kibale National Park, Uganda found feeding time devoted to Ficus mucuso was positively associated with availability, reinforcing the argument that chimpanzees are ripe fruit specialists. Expand

Demographic influences on the hunting behavior of chimpanzees.
TLDR
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. Expand
Predation on mammals by the chimpanzee (Pan troglodytes)
TLDR
It is suggested that the size or demographic trend of a chimpanzee unit-group necessarily influences its hunting frequency as well as its prey profile, and factors which bring these males together into a party strongly affect the actual hunting and kill rates. Expand
Hunting behavior of wild chimpanzees in the Taï National Park.
TLDR
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. Expand

HUNTING DECISIONS IN WILD CHIMPANZEES
TLDR
Evidence from Gombe National Park, Tanzania is presented showing that the social factors that most strongly influence the decision to hunt red colobus monkeys are the presence of female chimpanzees with anogenital sexual swellings in the foraging party, the number of adult and adolescent males in the party, and the total size of theforaging party.

Patterns of predation by chimpanzees on red colobus monkeys in Gombe National Park, 1982-1991.
TLDR
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. Expand
Rates of predation on mammals by gombe chimpanzees, 1972–1975
TLDR
Present data suggest that chimpanzees in Gombe and Tai National Park, Ivory Coast, prey on mammals at rates higher than other populations. Expand
Communal hunting and pack size in African wild dogs, Lycaon pictus
TLDR
In the Selous Game Reserve, Tanzania, wild dog pack size ranged from three to 20 adults (3–44 including yearlings and pups), data showed that hunting success, prey mass and the probability of multiple kills increased with number of adults. Expand
Chimpanzees-red colobus monkeys: a predator-prey system
TLDR
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. Expand
The behavioural ecology of chimpanzees in Gombe National Park, Tanzania
TLDR
Chimpanzees are found to have an intimate knowledge of their environment and its food sources; the data do not support previous suggestions that the function of dispersal and aggregation to locate foods is supported. Expand
