Environmental Enrichment

Recycled plastic cages and environmental enrichment devices

Although the production and use of recycled plastic lumber is still in its infancy, our experience indicates that this is an ideal material for the construction of environmental enrichment devices for monkeys ... especially in outdoor facilities and zoological collections.

Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Short-term evaluation of a foraging device for non-human primates

In the USA, any institution involved in using non-human primates for research has had, for regulatory reasons, to address the psychological needs of these animals. Enriching the environment through the use of foraging devices has been one method and a...

Frozen enrichment for chimpanzees

We gave this enrichment [frozen juice container] to 19 chimpanzees of different ages and found that it took from 24 to 48 minutes for each chimp to consume the frozen treat.

Lion-tamarin and marmoset enrichment at the National Zoo

As always, the key to successful enrichment is variety. Use a different device each day. Load it with different foods each time. Sometimes don't load it with anything at all! (It keeps them guessing.) Before you start, get a quantitative...

Environmental enrichment and exploration

An understanding of animals' information-gathering needs is an important element in the design of environmental enrichment programs. Animals should be provided with continuing novelty and variability, as well as an opportunity to have some control over their environment.

Small primate enrichment at the Calgary Zoo, part 3: patas and spider monkeys

Some feeding enrichment options are reported. Some animals leaped several feet to a fruit stuck on branches, even when fruit was freely available on the ground.
