Researchers have documented infanticide by adult males in four wild chimpanzee populations. [...] Key Result Both infanticides happended during boundary patrols, which occur at a high frequency there. Patrolling males attacked solitary females who were unable to defend their infants successfully. The victims were almost certainly not members of the Ngogo community. Males cannibalized both infants and completely consumed their carcasses.Expand
New cases of inter-community infanticide by Male Chimpanzees at Ngogo, Kibale National Park, Uganda
TLDR
Two new cases of infanticide by male chimpanzees at Ngogo, Kibale National Park are reported, consistent with the range expansion hypothesis: the infanticides occurred during a period of frequent encounters between communities associated with a mast fruiting event, and Ngogo community members greatly increased their use of areas near the attack site during another mast fruited event one year later.
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
Intra-community infanticide in wild, eastern chimpanzees: a 24-year review
TLDR
A full record of all intra-community infanticides and failed attempts at infanticide over a 24-year period for the Sonso community of chimpanzees in the Budongo Forest, Uganda is presented to test four hypotheses for this behavior: the sexual selection hypothesis, male mating competition, resource competition, and meat acquisition.
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
Infant killers of Budongo revisited: infanticide and counterstrategies in wild, eastern chimpanzees
TLDR
The majority of infanticides adhere to the predictions of the sexual selection hypothesis for male committed infanticide, that instability in the male hierarchy is a key risk factor, and that mothers, but not fathers employ counterstrategies to protect their infants.
An attempted within-group infanticide in wild chimpanzees
TLDR
The sudden disappearance of another infant, a healthy female, strongly suggests the killing of female infants too, and the asserted male-biased infanticide in chimpanzees appears to be less tenable.
Probable Community Transfer of Parous Adult Female Chimpanzees in the Budongo Forest, Uganda
Female chimpanzees with dependent offspring generally avoid border areas of their community's home range because they risk aggression and infanticide from extracommunity males. Typically, only
Infanticide in chimpanzees: Taphonomic case studies from Gombe.
TLDR
The cases described here suggest that chimpanzees may not always completely consume infanticide victims, while reports on chimpanzee predation indicated that complete consumption of monkey prey usually occurred.
Lethal intergroup aggression by chimpanzees in Kibale National Park, Uganda
TLDR
Data is added to the database on intergroup coalitionary aggression in chimpanzees by describing three fatal attacks on adult males, plus a fourth attack on an adult male and an attack on a juvenile that were almost certainly fatal.
Fatal Chimpanzee Attack in Loango National Park, Gabon
TLDR
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.

New records of within-group infanticide and cannibalism in wild chimpanzees
TLDR
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
TLDR
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.

A prolonged attack on a mother and 2-year-old infant that resulted in the death of the infant was observed in the Kanyawara study group in Kibale National Park. The mother was a border-area resident
Infant Killers of Budongo
TLDR
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.

TLDR
Data from an unusually large chimpanzee commmunity at Ngogo, Kibale National Park, Uganda, that contains more males than any previously studied community show new variation in chimpanzee mate-guarding behavior, and pairs or trios of top-ranking males sometimes engaged in cooperative aggression to prevent estrous females from mating with other males, but tolerated each other's mating activities.
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.
Female reproductive strategies, paternity and community structure in wild West African chimpanzees
TLDR
Pedigree relationships in that community of 55 wild chimpanzees in the Taï Forest, Côte d'Ivoire show that female mate choice strategies are more variable than previously supposed and that the observed social groups are not the exclusive reproductive units.
Male affiliation, cooperation and kinship in wild chimpanzees
Long-term field research has revealed that male chimpanzees, Pan troglodytes, affiliate and cooperate in several contexts. Assuming close genetic relationship among males, affiliative and cooperative

TLDR
The characteristics of the social group of wild chimpanzees are clarified by long-term observation of the baited population, and the permanency, stable membership, and integrative nature of the unit-group were confirmed during the course of this study.
