King Kong® rubber toys: An effective enrichment device for captive chimpanzees (Pan troglodytes)

Subjects were tested on one single occasion each when they had access to a toy for 15 minutes. High percentages of use by two chimpanzees adjacent to social groups suggest that the King Kong toy may be an especially effective...

Behavioral intervention program: Enriching the lives of captive nonhuman primates

Since its inception, 142 animals have been reported to the BIP [Behavioral Intervention Program, developed in 1994], including chimpanzees, baboons and other monkeys. The most common behaviors reported were hair pulling, pacing, rocking and self-aggression. 36.6% of the BIP subjects...

Social management of captive chimpanzees

This chapters describes both beneficial and potentially problematic outcomes related to different social environments for chimpanzees. Where possible, methods for addressing the behavioral problems [e.g., behavioral/maternal incompetence, aggression] that might be associated with particular choices of social environments [e.g., nursery...

Post-conflict behaviour of wild chimpanzees (Pan troglodytes schweinfurthii) in the Budongo Forest, Uganda

Since de Waal & van Roosmalen (1979) first documented the occurrence of reconciliation between former opponents in captive chimpanzees, the study of the post-conflict behaviour of primates has provided valuable information about some of the details of primate social organisation....

Living conditions affect stress levels of captive chimpanzees

Our results indicate that stress levels in captive chimpanzees are not affected by population density per se (chimpanzees use behavioural coping strategies), but when coupled with high Neighbor Effect stress levels increase. If many groups need to live in close...

Control vs. passive exposure to joystick-controlled computer tasks intended as enrichment for chimpanzees (Pan troglodytes)

This study aimed to test the effects of enhancing control, via joystick-controlled computer games. .. More time spent watching the monitor was associated with more social and lone play and object manipulation, and less inactivity. .. Under mildly stressful conditions,...

Chimpanzee facility design

A fundamental principle of this chapter is that design features should promote the expression of species-typical behavior and development. .. The design plan and the operational plan should evolve together.

Coping with short-tem space restriction in chimpanzees

During the indoor period the chimpanzees showed no increase in aggression, grooming, and submissive greeting, nor changed their proximity to adult males. However, the percentage of aggressive events that involved more than 2 individuals was significantly lower during the indoor...

Behavioral and environmental enrichment of individually housed chimpanzees

Ways to eliminate or reduce the need for individual caging, through housing changes, operant conditioning, and other procedures, are described. For situations in which individual caging cannot be avoided, an enhanced environmental enrichment program is necessary and some guidelines are...
