Despite considerable attention to chimpanzee intergroup violence, the number of observed cases remains small. We report 4 cases of intergroup violence that occurred in Gombe National Park, Tanzania, between 1993 and 2002. We observed (3 cases) or inferred (1 case) males from the Kasekela community to attack members of their 2 neighboring communities: Mitumba and Kalande. In 1993, Kasekela males killed and ate a female infant from Mitumba. In 1998, Kasekela males captured 2 infants (sex unknown… 
New Intercommunity Infanticides by the Chimpanzees of Ngogo, Kibale National Park, Uganda
Hostile intercommunity relations, including attacking and killing extra-community infants of both sexes have occurred at most wild chimpanzee sites. We describe three recent cases of intercommunity
Intergroup conflicts among chimpanzees in Taï National Park: lethal violence and the female perspective
A reconsideration of the difference in intergroup interactions between eastern and western chimpanzees is proposed including a more important consideration of the female's perspective and new parallels to be drawn with the evolution of primitive warfare in humans.
Death of the Alpha: Within‐Community Lethal Violence Among Chimpanzees of the Mahale Mountains National Park
The first account of the killing of an incumbent alpha male by a coalition of adult males from the same community is provided; the lethal attack triggered a period of instability in the male hierarchy and was likely an opportunistic attempt to seize alpha status by the third‐ranking male.

Intercommunity coalitionary killing of adult and adolescent males has been documented in two chimpanzee communities in the wild, and it was strongly suspected in a third. It may increase survivorship
New Case of Intragroup Infanticide in the Chimpanzees of Gombe National Park
Researchers have reported a total of 31 infanticides in 4 different chimpanzee (Pan troglodytes) populations. Though infanticide is infrequent, low reproductive rates of females likely make it a
Fatal Chimpanzee Attack in Loango National Park, Gabon
The combined observational and genetic evidence suggest an intercommunity attack on an adult male chimpanzee at a new research site in Loango National Park, Gabon, adding to the growing evidence that intercommunity killings are a rare but widespread phenomenon among chimpanzees and not an artifact of human provisioning or habituation.
Intercommunity interactions and killings in central chimpanzees (Pan troglodytes troglodytes) from Loango National Park, Gabon
First insights into intercommunity interactions of individuals of a community of central chimpanzees living in the Loango National Park in Gabon suggest that the frequency of lethal attacks at Loango is comparable to that reported for the eastern subspecies and female involvement in inter community interactions mirrors that of the western subspecies.
Causes of death in the Kasekela chimpanzees of Gombe National Park, Tanzania
It is found that the most important cause of mortality in the Kasekela community was illness, followed by intraspecific aggression, and most deaths due to illness occurred during epidemics, and the most common category of disease was respiratory.

Lethal intragroup aggression by adult male spider monkeys (Ateles geoffroyi)
Three cases of coalitionary aggression by adult male black‐handed spider monkeys (Ateles geoffroyi) against subadult males within their community on Barro Colorado Island, Panama are reported, which suggests that intense competition among males for access to reproductively viable females may be a contributing factor.


Incident of intense aggression by chimpanzees against an infant from another group in Mahale Mountains National Park, Tanzania
An unusual case of intense aggression against an infant male from another group by chimpanzees of the Mahale Mountains National Park, in Tanzania, where the infant was seriously injured and most likely died and two researchers were wounded.
New records of within-group infanticide and cannibalism in wild chimpanzees
It is proposed that the function of within-group male infanticide can be explained by the male-male competition hypothesis developed for hanuman langurs and other nonhuman primates.
Within-group cannibalism by adult male chimpanzees
Four such cases of within-group cannibalism by adult males suggest that the female range and association pattern before and after parturition are key factors allowing an infant to survive.
Does participation in intergroup conflict depend on numerical assessment, range location, or rank for wild chimpanzees?
Male chimpanzees, Pan troglodytes, engage in cooperative territorial defence and sometimes kill members of neighbouring communities. Observations of intergroup interactions suggest that escalation of

Demonic Males: Apes and the Origins of Human Violence
This study is an analysis of the roots of human savagery, dealing with the fundamental questions of why the majority of violence is perpetrated by men, whether this is a matter of nature or nurture
Infant Killers of Budongo
Two observations of infanticide by male chimpanzees in the Budongo Forest are reported here; the first detailed infanticides to be described for Budongo, where the infant was clearly the target; the mother was only assaulted to achieve this end, and was not seriously injured.
Why do male chimpanzees defend a group range?
Female life history and mating patterns among the M group chimpanzees of the Mahale national park, Tanzania
The mating behavior of receptive females in the M group chimpanzees (Pan troglodytes schweinfurthii) of the Mahale Mountains, western Tanzania, was studied by intensive sampling over a period of 5 months and gradual shift from opportunistic to restrictive matings after inter-unit-group transfer was revealed for 2 ex-K-group parous females.
Data from the five long-term sites with neighboring groups show that intergroup aggression is a pervasive feature of chimpanzee societies, including sites where artificial feeding never took place.
