Forage “shooter”: A means to widely distribute forage materials

A device was designed that allows us to blow forage [e.g., chicken scratch] into both empty and occupied cages and over a wide area.

Behavioral changes in captive chimpanzees

Overall, after the move to the larger [structurally enriched] facility, there was an increase in activity, a decrease in stereotypical behaviour, and an increase in threat behavior.

The nuts and bolts of captive chimpanzee diets and food as enrichment: A survey

Results suggest facilities are moving away from timed feeding schedules, which tend to increase prefeeding levels of agonism, to feeding a wide variety of food throughout the day and using a wide variety of feeding techniques.

Friendship’ for fitness in chimpanzees? Animal Behaviour 58, 1223-1229

It has been repeatedly suggested that primates trade social services for fitness benefits in their relationships with the opposite sex. We tested this proposal in a colony of captive chimpanzees,Pan troglodytes, by examining behavioural data on grooming, agonistic support and...

Coping with conflict during initial encounters in chimpanzees

When strangers meet, conflict is likely to arise from incompatibilities in motivations and expectations, as well as from the absence of predictability in interactions. This study explores the mechanisms that mitigate aggression, permit mutual evaluation, establish tolerance, and facilitate the...

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...
