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...

A rich ape is a happy ape

Chimpanzees were attracted to boxes right away, but quickly grew tired of them. In comparison, orangutans tore the boxes up, but used them even more after they were torn into several pieces.

The resocialization and rehabilitation of humanized and abused primates

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 portable cages), surrogate mothers, territorial...
