Use of temporary and semitemporary enrichment objects by five chimpanzees

The results of this study emphasize the importance of temporary object rotation and presentation of both temporary [paper, magazines, raisin boards, cardboard boxes, etc.] and semitemporary [nets, climbing structures, straw, grass, etc.] objects to captive chimpanzee environments. This work has...

Videotapes as enrichment for captive chimpanzees (Pan troglodytes)

Individually housed subjects watched the videotapes more than socially housed subjects. When viewing time was averaged across all videotapes, the chimpanzees watched the monitor a mean of 38.4% of the time available. ... Subjects habituated to repeated presentations of the...

Control over videotape enrichment for socially housed chimpanzees

Social behavior and solitary play were higher in subjects with control over the onset of videotapes, while scratching [generally regarded as a sign of tension] was higher in those groups who lacked control. The results indicate that giving chimpanzees control...

I’m forever blowing bubbles!

The chimpanzees are fascinated with the bubbles floating .... run around sticking out their tongues, much as a child collecting snowflakes, and attempting to catch them - a bit bewildered as it disappears.
