Small primate enrichment at the Calgary Zoo, part 2: Lemurs

Some enrichment options are reported. These lemurs require branches of a substantial size for resting on, as they usually like to lie flat on a branch with limbs dangling on either side for balance.

Stimulating natural behaviors: Enrichment for brains and hands

Observing that our animals were interested in the water gave us the idea of offering live feeder gold fish in the exhibit pools as a form of captive enrichment. When we introduced this activity, the adult male, Dom, a wild-caught...

Toys as environmental enrichment for captive juvenile chimpanzees (Pan troglodytes)

Whereas contact with the indestructible toy ball decreased over time, destructible objects maintained a consistent level of interest throughout the toys lifespan. ... Provision of both types of toys did not result in significant differences in the time individuals spent...

A statistical analysis of the effects of enrichment on primate behavior

The environment of any primate can be enriched with beneficial behavioral outcomes if care and an organized study effort is utilized in the enrichment selection process. Placing items in an exhibit for the monkeys to manipulate does not guarantee that...

Using the mesh ceiling as a food puzzle to encourage foraging behaviour in caged rhesus macaques (Macaca mulatta)

An attempt was made to encourage more foraging behaviour in eight pair-housed adult rhesus macaques (Macaca mulatta). No special device and no special food were used. Daily commercial dry food rations consisting of 33 bar-shaped or 16 star-shaped biscuits per...

Enticing nonhuman primates to forage for their standard biscuit ration

Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged in gathering the standard biscuit...
