Behavioral observation in a macaque breeding colony: Assessment of enrichment strategies

While the percentage of animals demonstrating one abnormal behavior in one month observation may reach 30%, the frequency of deleterious abnormal behavior [self-aggression, hair pulling, bizarre stereotypical behaviors] is low at 2.2% of the total population (N=1303). These animals are...

Living naturally: Aspects of wild environments relevant to captive chimpanzee management

Discussion of activity budgets of chimpanzees living in their natural habitat. The animals spend about 50% of the time feeding, 15% of the time resting, less than 15% of the time grooming each other.

Vegetables as dietary enrichment for Saimiri

In all cases vegetables were consumed quickly, with celery and bell peppers being the preferred vegetables, followed closely by squash. String beans required more effort to eat and were usually the last to be eaten. ... This study indicates that...

Quantitatively tested environmental enrichment options for singly-caged nonhuman primates: A review

Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide appropriate means for the expression...

Reduction of regurgitation and reingestion (R&R) in lowland gorillas at the Oklahoma City Zoo

The addition of browse or hay to the diet of captive gorilla reduces the occurrence of R&R [regurgitation-reingestion]. Novelty items tend to reduce R&R for short periods of time. Manipulation of how and when food items are presented reduces R&R.

Long-term use of enrichment for paired and singly caged chimpanzees

Chimpanzees used televisions, balls, and mirrors for 0.27-1.53% of the observation time after several years of exposure to the enrichment items. Television and ball use were significantly higher than mirror use.

Differences in behaviour among adult male, female pairs of cotton-top tamarins (Saguinus oedipus) in different conditions of housing

Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more active than those on the...
