Chimpanzee

Long-term use of enrichment for paired and singly caged chimpanzees

Chimpanzees used televisions, balls, and mirrors for 0.27-1.53% of the observation time after several years of exposure to the enrichment items. Television and ball use were significantly higher than mirror use.

Training as environmental enrichment for chimpanzees

Results indicated that training can be enriching for [group-housed] chimpanzees by increasing social play and reducing inactivity.

The disappearing ice cube

Ice cubes are distributed across the floor, hidden in high plastic barrels (we call these igloos), tucked into corners of the cages, etc. As the animals come out, the excitement of the hunt starts and continues until the last ice...

Pre-feeding agonism and seasonality in captive groups of chimpanzees (Pan troglodytes)

Enriching the environments of groups of captive chimpanzees by providing a variety of attractive foods (fruit) does not seem to increase tension or lead to increased pre-feeding agonism. Managers should be encouraged to provide a varied diet reflecting the food...

Psychological wellness for captive chimpanzees: An evaluative program

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 the provision of stimulation enrichment,...

Regurgitation and reingestion in a captive chimpanzee (Pan troglodytes)

Our findings suggest that behavioral training [negative/positive reinforcement] coupled with a dietary change [replacing fruit with vegetables and browse] may reduce regurgitation activities.

Space utilization and social behaviors of chimpanzees (Pan troglodytes) housed under varying caging and social conditions

Affiliative behaviors and ambulatory activity were significantly greater when groups [one male plus 2 or 3 females] had less space. When they had access to several cages, the animals spend most of the time in one cage in close proximity...
