This study compared the effectiveness of kraft wrapping paper and rubber to as enrichment for 22 chimpanzees group-housed in conventional indoor/outdoor runs. Objects were tested separately during 67 hours of data collection using a group...
Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide...
Authors describe the "Wellness Program" of the Primate Foundation of Arizona (PFA) devoted to producing physically and behaviorally normal chimpanzees. Psychological well-being is a major focus. In this paper, the authors present protocols specific to...
Author presents case histories of Primarily Primate's treatment of individual primates with problems common to humanized and abused primates. Among the methods effectively used were gradual introduction to other primates, (sometimes with the use of...
Review of the implications of experimental or management-related manipulations of the social environment of captive primates for the animals' welfare. Relatively little empirical work has been done on the effects of manipulation of the social...
The social environment [which includes the care providers] is perhaps the most critical factor in chimpanzee well-being, more important even than designs of the living space.
Training technique is described. Thirty-seven [group-housed] captive chimpanzees were trained using operant conditioning to enter a transfer box. [Age and sex of subjects is not provided.]
In the wild, chimpanzees spend most of their time foraging, so any device that stimulates this behaviour in captivity could potentially be effective enrichment. A simple grass foraging device constructed of a polyvinyl chloride (PVC)...
The purpose of this article is to illustrate how recycled, throw-away, and donated materials have been used creatively at little cost for the daily enrichment of chimpanzees.
Enrichment items are thoroughly examined for potential hazards.
