The behavior of captive male chimpanzees (Pan troglodytes) housed in multi-male bachelor versus mixed-sex social groups at the Primate Foundation of Arizona

As juveniles, avoidance/fear was greater for males housed in mixed-sex groups. As adults, aggression was significantly greater for males housed in multi-male groups.

Chimpanzees and retirement

The information on group formation is readily available, and several sanctuaries exist that can provide appropriate models for retirement. What has not been available to date is a commitment to the long-term care of chimpanzees that translates into dollars to...

Variables influencing the origins of diverse abnormal behaviors in a large sample of captive chimpanzees (Pan troglodytes)

Rocking and self-sucking were significantly more likely in hand-reared animals. Coprophagy and depilation of self were significantly more likely in mother-reared animals. ... The only significant sex difference was a higher prevalence of coprophagy in females and a higher prevalence...

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...
