Abnormal behavior in a captive chimpanzee colony

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers had less abnormal behavior. Access...

Utilization of a sensory diet approach for enrichment and mitigation of abnormal behaviors in captive chimpanzees (Pan troglodytes)

Treatment consisted of stimulation of the tactile senses through use of various paper media, a combing/brushing schedule and muscle pressure techniques. A reduction in the rate of coprophagive events was observed.

Positive reinforcement training to enhance the voluntary movement of group-housed chimpanzees within their enclosure

Positive reinforcement techniques are described and were applied to train groups of chimpanzees to move voluntarily into the indoor portions of their enclosures at the request of trainers and to be briefly restricted to those areas. ... Females required significantly...

Enlarging chimpanzee social groups: The behavioral course of introductions

All 42 introductions of chimpanzees (aged 3-43 years) in already established groups were successful. New group members were first introduced behind mesh fencing. Subsequent full physical contact did not further increase agonism. Stereotyped rocking declined in newly integrated individuals.

Outdoor access: The behavioral benefits to chimpanzees

When compared to the results of ameliorative environmental enrichment techniques furnished to the indoor-housed subjects, the small outdoor groups of [two or three] chimpanzees showed broader and more dramatic improvements in well-being. Animals with outdoor access showed significantly less abnormal...

Requirements of biomedical research in terms of housing and husbandry for non-human primates: Pharmacology & Toxicology

The objective of toxicology and pharmacology studies is to detect change or variation from normal and to interpret the significance of such change, with the intention of assessing risk to man. With non-human primates (NHPs) detection of change related to...

Please don’t touch, we’re being enriched! In: Proceedings of the International Conference on Environmental Enrichment

Enrichment often involves manipulation of animals' lives. However, non-interference in their social lives is an important form of environmental enrichment for chimpanzees. Rather than locking the chimpanzees into their indoor cages every evening, an average of 17 hours a day...

Destructible toys as enrichment for captive chimpanzees

Nine singly caged chimpanzees were provided with eight different toys made of plastic, vinyl, or cloth one at a time or several at once. The toys remained in the cages an average of three days. The chimpanzees varied greatly in...
