Predation by female chimpanzees: Toward an understanding of sex differences in meat acquisition in the last common ancestor of Pan and Homo
Reproductive state and rank influence patterns of meat consumption in wild female chimpanzees (Pan troglodytes schweinfurthii)
The energetic and nutritional yields from insectivory for Kasekela chimpanzees
Primates, insects and insect resources
Why do chimpanzees hunt? Considering the benefits and costs of acquiring and consuming vertebrate versus invertebrate prey
Responses of chimpanzees to a recently dead community member at Gombe National Park, Tanzania
Chimpanzee responses to the death of a group member have rarely been observed in the wild and most instances involve infant deaths. One of the very few detailed accounts of a group's response to the death of an adult community member is from Gombe National Park, Tanzania, where Teleki [Folia Primatologica 20:81–94, 1973] observed the responses of 16 chimpanzees to an accidental death, none of whom touched the body. Now, almost 40 years later, we …
Nutritional composition of actual and potential insect prey for the Kasekela chimpanzees of Gombe National Park, Tanzania
Humans, all great ape species, and some lesser apes consume insects. Insects can provide comparable nutritional yields to meat on a gram‐for‐gram basis and may serve as an important source of energy, fat, protein, minerals, and vitamins for hominoids. Although potential insect prey are abundant in ape habitats, patterns of insectivory are not consistent across species or populations. Efforts to understand these patterns are complicated by a lack …
The Appearance and Spread of Ant Fishing among the Kasekela Chimpanzees of Gombe: A Possible Case of Intercommunity Cultural Transmission
Chimpanzees exhibit cultural variation, yet examples of successful cultural transmission between wild communities are lacking. Here we provide the first account of tool-assisted predation ("ant fishing") on Camponotus ants by the Kasekela and Mitumba communities of Gombe National Park. We then consider three hypotheses for the appearance and spread of this behavior in Kasekela: (1) changes in prey availability or other environmental factors, (2) …
Sleeping tree choice by Bwindi chimpanzees
Unlike nearly all other nonhuman primates, great apes build sleeping nests. In Bwindi Impenetrable National Park, Uganda, chimpanzees build nests nightly and also build day nests. We investigated patterns of nest tree use by Bwindi chimpanzees to understand ecological influences on nest tree selection. We analyzed data on 3,414 chimpanzee nests located from 2000 to 2004. Chimpanzees at Bwindi were selective in their use of nest trees. Of at least…
Plant Species with Potential as Food, Nesting Material, or Tools at a Chimpanzee Refuge Site in Caddo Parish, Louisiana
Hand preferences in captive orangutans (Pongo pygmaeus)
Evaluating social influences on food-processing behavior in white-faced capuchins (Cebus capucinus)
Interpopulation variability in patterns of food processing, similar to what is described as "traditional" or "cultural" variation in chimpanzees (Pan troglodytes) and orangutans (Pongo pygmaeus), was identified in white-faced capuchins (Cebus capucinus). However, recent comparisons of food processing in capuchins were conducted only at the population level, with relatively little attention given to variability among groups, age/sex classes, or in…
Variability in food‐processing behavior among white‐faced capuchins ( Cebus capucinus ) in Santa Rosa National Park, Costa Rica
Observed patterns of variability in the food‐processing behavior of white‐faced capuchins ( Cebus capucinus ) across populations may reflect foraging traditions. However, there has been relatively little attention given to intrapopulation variability in food processing among groups and age/sex classes, making recent cross‐population comparisons difficult to interpret. In this paper, we provide data on patterns of object use in foraging that we ob…
