Frequent hunting of red colobus monkeys (Procolobus rufomitratus) takes place at all long-term chimpanzee (Pan troglodytes) study sites where both species are present. Red colobus are the most commonly selected prey of chimpanzees even when other monkey species are more abundant. In particular, the chimpanzee community at Ngogo, Kibale National Park, Uganda, preys heavily on red colobus monkeys: the chimpanzee hunting success rate is extremely high, and chimpanzees kill many individuals per… 
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.
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.
Primate population dynamics over 32.9 years at Ngogo, Kibale National Park, Uganda
TLDR
Census data support the conclusion that the red colobus decline was caused primarily by chimpanzee predation, and demonstrate the importance of long‐term monitoring in understanding population dynamics and the role of intrinsic variables in shaping the species composition of a community.
Physiological and Behavioral Effects of Capture Darting on Red Colobus Monkeys (Procolobus rufomitratus) with a Comparison to Chimpanzee (Pan troglodytes) Predation
TLDR
Data show that darting and collaring and a chimpanzee predation attempt caused an acute stress response, but neither leads to sustained elevated cortisol levels, and capture darting appears to be a useful technique with minimal long-term effects as long as injury and mortality are avoided.
The Hunting Behavior and Carnivory of Wild Chimpanzees
TLDR
Very little is known about hunting of non-primates, particularly ungulates, or the impact that variation in levels of hunting, and of carcasses to share and consume, has on patterns of chimpanzee behavior, so efforts to understand the diversity of hunting and carnivory in wild chimpanzees are needed.
Chimpanzees and their mammalian sympatriates in the Issa Valley, Tanzania
TLDR
Estimating likely chimpanzee encounter rates with sympatric mammals in the Issa Valley, Tanzania, through modelling actual researcher encounter rates is compared to published literature and contextualise them in light of reconstructing diverse mammalian communities in which hominins lived during the Plio‐Pleistocene and the use of chimpanzees as flagship species for conservation policy.
Hunting Activity Among Naturalistically Housed Chimpanzees (Pan troglodytes) at the Fundació Mona (Girona, Spain). Predation, Occasional Consumption and Strategies in Rehabilitated Animals
TLDR
It is confirmed that naturalistic environments allow chimpanzees to enhance species-typical behavioral patterns in a naturalistic environment without learning it in the wild.
Long-Term Research on Chimpanzee Behavioral Ecology in Kibale National Park, Uganda
TLDR
Kibale data is compared to those from other long-term chimpanzee research sites for providing valuable insights into demographic influences on behavior and on male reproductive success and into chimpanzee-red colobus predator–prey dynamics.

The impact and implications of vehicle collisions on the endangered and endemic Zanzibar red colobus (Piliocolobus kirkii)
TLDR
Mortality from collisions with vehicles in some groups of colobus are comparable to rates of mortality experienced by other primate populations from natural predation, however, vehicles are not ‘selective’ in their targeting of ‘prey’.

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.
Hunting Behavior of Chimpanzees at Ngogo, Kibale National Park, Uganda
TLDR
The first quantitative support for the argument that variation in canopy structure influences decisions to hunt red colobus is provided, and implies that the chimpanzees hunt most when they can easily meet energy needs from other sources.

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.

TLDR
The hypothesis that the changes in red colobus and blue monkey density are due to changes in the forest structure and abundance of their most selected feeding trees is tested, and it is shown that changes in forest composition cannot account for changes in their red Colobus abundance.

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.

TLDR
The results of this study illustrate that the nature of the costs and benefits of polyspecific associations for these different monkey species are complex and vary from species to species.
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.
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.
