Environmental structure influences use of multiple video-task devices by socially housed pigtail macaques

The video-task paradigm does appear to be a useful method of promoting environmental enrichment for social groups of captive primates. Our data suggest that the cage front, while often convenient, may not optimize enrichment potential. We hypothesize that our subjects...

Primary forage feeder for singly-caged macaques

Perforated feeder box requires the single-housed subject to use the fingers to maneuver biscuits to access holes at different levels. Apparently the animals consumed nearly all the food retrieved from the forage feeders, leaving less on the cage floor to...

Optimal foraging in the captive-bred common marmoset, Callithrix jacchus

The dominant pair, when given the choice, preferred to forage from the high-level box [filled with deep litter containing raisins], allowing the other group members to forage mainly at ground level. .. When feeding at floor level the marmosets took...

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...

Letter to the Editor

Biologists who design studies to compare cage sizes should remember that in nature these animals live in a complex arboreal environment .... To determine whether cage size is important, comparisons should be made between macaques in cages and macaques housed...

Technical management of an owl monkey breeding colony in a research laboratory

The compatibility of prospective pairs was determined by trial and error prior to permanent pairing, that is, by placing the pair into an observation cage along with treats such as bananas and marshmallows. If fighting occurred, the trial pair was...

Psychological well-being and other projections of the human condition: Their meaning for research activities with non-human primates

The often cited paradox for researchers studying nonhuman primates is that we must consider them sufficiently similar to us so that our studies will be valid and significant; at the same time we must consider them sufficiently different that we...
