Training rhesus macaques for the pole and collar system

I trained two [adult] male Rhesus over the past year with the pole and collar system and neither of them need the squeeze mechanism to hook their collar. One of them sits still and waits for me to hook his...

Behavioral effects of simple manipulable environmental enrichment on pair-housed juvenile macaques (Macaca nemestrina)

The teddy bear was preferred as a manipulable toy over the pink teething ring and the green teething ring. Toy use declined with time, indicating that rotation of toys, at least in the short term, may increase use.

Pairing female Macaca nemestrina

Twenty-four adult pig-tailed macaques are successfully transferred from single- to pair-housing arrangements. We have observed no serious fighting and wounding in our pairs, neither at the moment of introduction nor during follow-up observations of up to two years. ... Pairs...

Crowding stress and violent injuries among behaviorally inhibited rhesus macaques

A rhesus group of 36 animals was kept during 6 'warm' months in a large outdoor enclosure, during 6 'cold' months confined in a building. During the 6-month period of confinement stress, a fivefold acceleration in [medically-attended] injury incidence was...

Differences in stress reactivity of laboratory macaques measured by heart period and respiratory sinus arrhythmia

Exposure to an unfamiliar technician with capture gloves stimulated cardiac reactivity more strongly than an intense sound. ... Behavior responses to the glove indicated that all subjects consistently perceived this 'ecologically relevant' stimulus as threatening.

Evaluation of stainless steel reflective discs as enrichment devices for rhesus monkeys (Macaca mulatta) housed in a toxicological facility

The enrichment device was used [probably by single-caged subjects] primarily for manipulation and banging. ... The usage of polished stainless steel discs declines over time and therefore alternative methods of environmental enrichment and rotation of enrichment devices should be considered.

Food and feeding behaviour of the pig-tailed macaque (Macaca nemestrina leonina) in semi-evergreen forest in Bangladesh

This subspecies is completely arboreal and frugivorous. The group spent 21.7% of their daily active time on feeding and 39.6% time on foraging.

Psychological well-being of captive nonhuman primates

Merely increasing cage size has not been associated with meaningful improvements in psychological well-being among singly housed macaques. Environmental change, such as being moved into a new room, disturbs monkeys, as demonstrated by appetite suppression, disruption of the normal activity...
