Rigid plastic balls as environmental enrichment: A novel presentation

At the Primate Foundation of Arizona (PFA), we provide many different types of both destructible and indestructible objects, but seldom provide rigid plastic balls. They are frequently thrown about the enclosure during displays and have damaged the cage mesh. We...

Initiating a computer-assisted enrichment system for captive chimpanzees

The joystick apparatus was used without significant decrease throughout 2-hour sessions and across the 3-month duration of the study. ... Food rewards were automatically dispensed upon completion of each trial. Juvenile subjects spent 20% of the 2-hour sessions utilizing the...

Blood collection procedure of laboratory primates: A neglected variable in biomedical research

A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so haphazardly that it would be...

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,...
