Diet and Foraging in the Waibira Chimpanzee Community, Budongo Central Forest Reserve, Uganda
Foraging is a fundamental aspect of the behavioural ecology of any species. Chimpanzees ( Pan troglodytes ) are generalist omnivores that inhabit a continuous range of forest environments. Accordingly, substantial differences in feeding ecology exist across chimpanzee sub‐species and populations. Despite a persistent importance for the role of ripe fruit, chimpanzee diets typically include a large variety of food types. While considerable data ex…
Understanding Cultural Transmission in Anthropology: A Critical Synthesis
The concept of "cultural transmission" is central to much contemporary anthropological theory, since successful human reproduction through social systems is essential for effective survival and for enhancing the adaptiveness of individual humans and local populations. Yet, what is understood by the phrase and how it might best be studied is highly contested. This book brings together contributions that reflect the current diversity of approaches …
Intra-community infanticide in wild, eastern chimpanzees: A 24-year review
Infanticide is well documented in chimpanzees and various hypotheses have been proposed to explain this behavior. However, since infanticide by chimpanzees is relatively rare, it has thus far not been possible to thoroughly test these hypotheses. Here we present an analysis of the largest dataset of infanticides from a single community of chimpanzees, a full record of all intra-community infanticides and failed attempts at infanticide over a 24-y…
Countering infanticide: Chimpanzee mothers are sensitive to the relative risks posed by males on differing rank trajectories
OBJECTIVES: Infanticide by males is common in mammals. According to the sexual selection hypothesis, the risk is inversely related to infant age because the older the infant, the less infanticide can shorten lactational amenorrhea; risk is also predicted to increase when an infanticidal male's chance of siring the replacement infant is high. Infanticide occurs in chimpanzees (Pan troglodytes), a species in which male dominance rank predicts pater…
Modeling Social Dominance: Elo-Ratings, Prior History, and the Intensity of Aggression
Among studies of social species, it is common practice to rank individuals using dyadic social dominance relationships. The Elo-rating method for achieving this is powerful and increasingly popular, particularly among studies of nonhuman primates, but suffers from two deficiencies that hamper its usefulness: an initial burn-in period during which the model is unreliable and an assumption that all win–loss interactions are equivalent in their infl…

The Hunting Behavior and Carnivory of Wild Chimpanzees
Death of the Alpha: Within‐Community Lethal Violence Among Chimpanzees of the Mahale Mountains National Park
Chimpanzees (Pan troglodytes) are capable of extreme violence. They engage in inter-group, sometimes lethal, aggression that provides the winners with an opportunity to enlarge their territory, increase their food supply and, potentially, attract more mates. Lethal violence between adult males also occurs within groups but this is rare; to date, only four cases (three observed and one inferred) have been recorded despite decades of observation. I…
Paternity and social rank in wild chimpanzees ( Pan troglodytes ) from the Budongo Forest, Uganda
We analyzed patterns of paternity and male dominance rank in the Sonso community of wild East African chimpanzees ( Pan troglodytes schweinfurthii ) in the Budongo Forest, Uganda. Our major objective was to determine whether and how social rank influenced paternity success. We successfully genotyped 52 individuals at up to nine microsatellite loci, using DNA extracted from fecal samples. Of 24 offspring analyzed, we identified sires for 21. Pater…
Chimpanzee Hunting Behavior
Female Coalitions Against Male Aggression in Wild Chimpanzees of the Budongo Forest
Probable Community Transfer of Parous Adult Female Chimpanzees in the Budongo Forest, Uganda
Fruit sharing between wild adult chimpanzees (Pan troglodytes schweinfurthii): A socially significant event
Although food sharing is a habitual aspect of chimpanzee (Pan troglodytes) life, sharing of plant foods between unrelated adults is rare. Observations of such behavior have typically been interpreted as the outcome of a process by which individuals that are otherwise unable to gain access to the food manage to obtain a nutritional benefit. Here we present behavioral details and an acoustic analysis regarding an observation of food sharing between…
