Food sharing and reciprocal obligations among chimpanzees

Food sharing has been proposed as the propeller of hominid evolution, particularly of the development of systems of mutual social obligation. Yet, food sharing in our closest relative has never been subjected to a rigorous analysis of reciprocity. Provisioning of...

Resocialization of captive chimpanzees: An amelioration procedure

Group formation protocols are described. 59 of 60 chimpanzees were successfully resocialized to compatible group living. Severe wounding has not occurred in our facility, perhaps due to luck, but more likely due to the close daily behavioral monitoring of each...

Signs of enrichment: Towards the psychological well-being of chimpanzees

By providing the chimpanzees with a wide variety of things to do we have also created an environment that is conducive to interesting social interaction. This is exactly the type of environment one would expect to help a chimpanzee achieve...

Chimpanzees in captivity: Humane handling and breeding within the confines imposed by medical research and testing

The ultimate touchstone for the psychological well-being of chimpanzees should be the ability of formerly singly caged animals to integrate into social groups after release into a (simulated) free environment, such as man-made islands.

Uprooted trees facilitate the psychological well-being of captive chimpanzees

Group-housed subjects used the tree during 41.9% of the data points collected during the first day trees were introduced. Thereafter, the mean for trees use dropped to 3.5% and remained fairly consistent.

Food puzzle device simulating termite fishing for captive chimpanzees (Pan troglodytes)

Significant reductions of abnormal behavior and significant increases in activity occurred with the pipe feeder's availability. Species-typical tool-using activity occurred, and the use of the pipe feeder increased subjects' foraging and feeding activity toward more species-normative levels. In the corral-housed...

On the care of captive chimpanzees: Methods of enrichment

Television can be a great source of environmental enrichment if the chimpanzee can perceive the relevance of what it sees on the screen to the world it knows.

Psychological well-being of primates in captivity

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no consensus presently exists in terms...
