Practical aspects of the program to promote psychological well-being in nonhuman primates at the Oregon Regional Primate Research Center

A comprehensive inanimate and animate enrichment program for rhesus macaques is described and valuable recommendations made to facilitate optimal psychological well-being throughout the animals' lives. A successful (80% compatibility) pair formation protocol for female rhesus macaques is outlined. New pairs...

Behavioral effects of perches on group-housed adult female Japanese monkeys

When [4 adult female] monkeys were housed in a cage which contained eight wooden perches to increase usable space, the rate of agonistic interactions as well as the rates of spatial proximity and social grooming decreased in comparison with those...

Cage toys reduce abnormal behavior in individually housed pigtail macaques

Providing multiple manipulable toys as enrichment for [single-caged] pigtail macaques was effective in reducing abnormal behavior during 30- min observation session. The use of the toys was reduced over time. The Kong toy was used most consistently.

Zoos, enrichment, and the skeptical observer

Increasing cage size as a means by which to enrich and enhance an animal habitat may not be worth the cost, at least under conditions in which the size of the cage is the only aspect that is altered. ......

Behavioral enrichment for ruffed lemurs, Varecia variegata, by using a more naturalistic method of food presentation

By providing whole rather than chopped fruits, a greater range of postures and increased manual manipulation of dietary items could be obtained. Time spent feeding and foraging also increased significantly.
