When trying to get your monkeys to behave, try perches

Higher perching elevations appear to be a very desirable feature in this environment for the expression of six of the twelve behaviors studied. Mid-level perches, on the other hand, were utilized more for only two of the behaviors: self play...

Caged stumptailed macaques voluntarily work for ordinary food

Ninety-nine of the biscuits were placed in a freely accessible dish attached to the mesh of the front of the cage. Thirty-three biscuits were offered in a food puzzle. Twenty-five percent (4/16) of the subjects ignored the food puzzle during...

Effects of enrichment on veterinary treatment of laboratory rhesus macaques (Macaca mulatta)

For captive primates, environmental enrichment may improve psychological well-being, as indicated by changes in the frequency of species-typical and abnormal behaviours. The effects of enrichment on physical well-being have also been examined, but little attention has been devoted to the...

Behavioral effects of enrichment on pair-housed juvenile rhesus monkeys

Environmental enhancers were frequently utilized, and led to relatively small changes in behavior between control and enriched subjects, suggesting that the presence of a partner for juvenile rhesus monkeys acts as a form of enrichment that may dilute the effects...

Effective environmental enrichment for caged rhesus macaques

The animals spent approximately 20% of the [day] time interacting with the companion, 10% perching on the PVC pipe, 4% gnawing/manipulating the branch segment and 7% foraging for primary food.

Caged rhesus macaques voluntarily work for ordinary food

Eight single-caged adult rhesus macaques were given the choice of freely collecting their standard food ration, i.e. 33 biscuits, from an ordinary food box or working for its retrieval from a custom- made food puzzle. During a one-hour observation session...
