Nonhuman Primate

Behavioral responses by singly-housed adult rhesus macaques (Macaca mulatta) during human interaction and positive reinforcement training

Males complied with significantly more commands, and overall learned significantly more basic husbandry commands than females. Trainers should expect agonistic responses to increase throughout the training process.

Chapter 4.17. Vertical Space Enhancement

Most of the primates' natural environment is fixed. Even a tree is fixed; it's only at the end of branches where a monkey in nature would have the sensation of anything like a swinging perch. A fixed perch is a...

The response to different environmental enrichments in the common marmoset (Callithrix jacchus): comparison among laboratory and zoo colonies

Different factors can influence the behavioural needs of captive marmosets, and therefore the effectiveness of a particular enrichment

Chapter 4.3. Feeding Enrichment

I have given whole watermelons to group-housed rhesus, cynos, bonnet and stump-tailed macaques for several years without noticeable adverse effects. It would be a waste of time to cut the melons into small pieces. The monkeys first gnaw a hole...

Early predictors of self-biting in socially-housed rhesus macaques (Macaca mulatta)

The subjects were 370 rhesus macaques born at the National Institutes of Health (NIH) Animal Center between 1994 and 2004. They were reared under three conditions: mother-reared in social groups (n=183), peer-reared in groups of four (n=84), and surrogate-peer-reared (n=103)....

Chapter 4.7. Windows

We expose our squirrel monkeys to natural daylight via big windows during the summer. This is supplemented with artificial light in late fall and early spring, when the days are short, and throughout the winter. Some of our squirrel monkeys...

The expression of self-injurious behavior in Macaca mulatta: prevalence, risk factors, and context

Self-injurious behavior (SIB) such as self-biting and self-wounding has been observed in a small, but persistent, percentage of captive nonhuman primates. Although biting often looks severe, not all self-biters wound themselves. Risk factors for SIB in rhesus macaques were investigated...

All of our single-housed long-tailed macaques have mirrors mounted on swivels that are attached to the outside of their cages, low enough so that an animal can chose to either bend down and intentionally look into the mirror or to...

Rhesus don't care much about coconuts, but stump-tailed macaques are fascinated by them and do not get tired working on them until the last morsel has disappeared in the drop pan. It never occurred that one of the monkeys somehow...
