The successful introduction of five male lion-tailed macaques (Macaca silenus) at Woodland Park Zoo

Male lion-tailed macaques (Macaca silenus) are notoriously aggressive and thus, few attempts have been made to house them together as adults. At Woodland Park Zoo in Seattle we had five surplus males with which we were able to successfully form...

Food distribution, dominance, and aggressive behaviours in bonnet macaques

Dispersing the food throughout the enclosure, rather than distributing it in one location, resulted in a decrease in agonistic interactions.

The use of videotapes as enrichment for singly housed chimpanzees

Each of six adult group-housed chimpanzees was placed in a single cage for 20-minute sessions during which a variety of videotapes were shown. The chimpanzees' response varied according to individuals and content of tape.

Successful feeding enrichment for captive chimpanzees

Four feeding techniques were simultaneously implemented: Corn on the cob/celery/artichokes, biscuits at libitum, sunflower seeds and peanuts spread in the grass, and puzzles filled with treats. Agonistic, abnormal, and grooming behaviors were significantly reduced.

An examination of various foraging components and their suitability as enrichment tools for captively housed primates

Vertically mounted foraging racks are described. Feeding enrichment devices were developed in tested. Vertically mounted foraging racks are beneficial because they increased locomotion, decreased hoarding, and appeared to increase the [group-housed] animals' interest in the feeding task.

Cage enrichment, behavior, and physiology in nursery-reared rhesus monkeys

Calm [single-caged] control animals and stressed [single-caged] enriched animals exhibited higher cortisol values. The enriched animals had lower cortisols when they appeared calm and higher cortisols when they appeared stressed.

Persistent sympathetic nervous system arousal associated with tethering in cynomolgus macaques

Persistent elevation in heart rate associated with tethering appears to be the result of a persistent influence of the sympathetic nervous system on cardiac function. .... Other organs and systems, e.g., pituitary-gonadal system, also may be affected.

Differential behavioral and adrenocortical responses to stress among three macaque species

Training technique is described to ensure that single-housed subjects voluntarily entered a transfer box. Bonnets took longer to train than rhesus or crabeaters.

Visitors excite primates in zoos

Fifteen species of primate were observed to assess the effects of zoo visitors on their social behavior. When visitors were present primates were less affiliative, more active, but more aggressive. These changes were particularly marked in arboreal monkeys. It is...
