Long-term effects of a natural foraging task on aggression and stereotypies in socially housed pigtail macaques

A supplementary feeding of approximately one cup of sunflower seeds were dispersed throughout the cage in the woodchip bedding in the middle of the afternoons, 4-6 hours after the group was fed their daily ration of chow and fruit. ......

Comparison of the physical characteristics of grooming in two species of macaques (Macaca nemestrina and M

Author examined social grooming in groups of bonnet and pigtail macaques to test hypothesis that the physical aspects of grooming (body sites, postures, methods) evolved in more aggressive species of primates to serve social functions (proximity maintenance and tension reduction)....

Interaction between adult male and immature captive chimpanzees: Implications for housing chimpanzees

These observations suggest that captive adult male chimpanzees have the potential to develop affiliative relationships with immature conspecifics. Housing adult males in groups along with infants may be an important way of increasing the social complexity of the males' environments.

Moving callitrichid monkeys from cages to outside areas

All animals avoided areas with little cover. The two tamarin families preferred an indoor cage to a large open area with little cover and consequently only showed a limited range of behavior when outside. When dense cover was provided to...

Enrichment in chimpanzees: Unpredictable ropes and tools

Chimpanzees preferred to play with ropes which acted unpredictably because the distant ends were in cages of other chimpanzees. Normal ropes were ignored.
