The use of videotapes as enrichment for singly housed chimpanzees

Each of six adult group-housed chimpanzees was placed in a single cage for 20-minute sessions during which a variety of videotapes were shown. The chimpanzees' response varied according to individuals and content of tape.

Successful feeding enrichment for captive chimpanzees

Four feeding techniques were simultaneously implemented: Corn on the cob/celery/artichokes, biscuits at libitum, sunflower seeds and peanuts spread in the grass, and puzzles filled with treats. Agonistic, abnormal, and grooming behaviors were significantly reduced.

Use of novel objects to enhance environments of captive chimpanzees

Following their familiarization with the novel objects [rubber or plastic toys for small children], the [group-housed] chimpanzees' manipulation frequency decreased whereas self-grooming and abnormal behaviors were increased. The importance of a periodical substitution of the objects was suggested to enhance...

Enrichment in chimpanzees: Unpredictable ropes and tools

Chimpanzees preferred to play with ropes which acted unpredictably because the distant ends were in cages of other chimpanzees. Normal ropes were ignored.

Evaluation of two environmental enrichment devices for singly caged chimpanzees (Pan troglodytes)

The television had a less pronounced effect on behavior [reducing behavioral disorders and increasing activity of the single-housed subjects] than the toys.

Interaction between adult male and immature captive chimpanzees: Implications for housing chimpanzees

These observations suggest that captive adult male chimpanzees have the potential to develop affiliative relationships with immature conspecifics. Housing adult males in groups along with infants may be an important way of increasing the social complexity of the males' environments.

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...
