A community-based occupational enrichment program for captive chimpanzees

Providing sufficient materials for a relatively large number [76] of animals can be difficult and costly in terms of staff time and materials. To relieve the financial burden, our enrichment program relies on donated materials or those purchased at relatively...

Affiliative social contagion in captive chimpanzees (Pan troglodytes): The happy neighbor effect

Both studies found a significant positive correlation between grooming in the focal group and grooming vocalizations in neighboring social groups (p < 0.01). Results suggest grooming vocalizations may be a mechanism for social contagion in chimpanzees. Research continues to test...

Captive chimpanzee social group formation

Forming new social groups of captive chimpanzees requires appropriate facilities, a knowledgeable staff, planning, and careful observations. A well-tested socialization system is reviewed which includes a gradual acclimation of unfamiliar chimpanzees and introductions in a controlled setting. The process has...

The use of positive reinforcement techniques with chimpanzees for enhanced care and welfare

Training is teaching. Teaching in a positive reinforcement-based system relies on gaining the voluntary cooperation of the chimpanzees during procedures, such as injection, blood collection, auscultation or urine sampling, or husbandry-related situations such as cooperative feeding. Several positive reinforcement training...

Control over videotape enrichment for socially housed chimpanzees: Subsequent challenge tests

The lower expression of stress-related behaviors by chimpanzees that took advantage of the opportunity to control the videotape apparatus implies that exerting control over the environment may have a generalized effect by lessening disturbance caused by mildly challenging situations.

Effect of enclosure size and complexity on the behaviors of captive chimpanzees (Pan troglodytes)

Changes in behavior of 5 adult chimpanzees that coincided with transfer to a larger, complex environment are described. The percentage of time spent traveling nearly doubled in the larger enclosure. The animals used all structures and all areas in the...

Mr. Sockies for Chimpanzees

The Primate Foundation of Arizona (PFA) makes Mr. Sockies for chimpanzees. They consist of a food treat (popcorn, pretzel, crackers, etc...) knotted inside a sock or small piece of fabric (10' or less). The legs of old jeans work well....
