Conspecific introduction, socialization, and attempts to breed a solitary-raised, silverback male gorilla

Even though the silverback Colossus had not had an opportunity to interact with any other gorilla since infancy, his introduction to the adult female conspecific Muke was very successful. The careful pair formation procedure is described.

Preliminary evaluation of Prima-Hedron play structures for non-human primates

Description of commercial roto-molded polyethylene structures serving as swing toys. The Prima-Hedrons' greatest virtues are that they can be assembled in so many ways that novelty is not restricted, and they can therefore maintain the interest of the monkeys using...

Designing captive primate environments sensitive to age and gender related activity profiles for rhesus monkeys (Macaca mulatta)

An analysis of the time budget (agonistic behavior is excluded) of rhesus macaque groups kept in free-ranging and confined [corncrib] condition. Adult animals spent about the same amount of time engaged in social grooming in both conditions (17%) but spent...

Are brief threating events beneficial for captive tamarins?

Cotton-top tamarins living in four families were observed following stimulating husbandry procedures [capture, birds passing overhead]. Arousal led to an improvement in behaviour (i.e., decrease in activity and an increase in affiliation) during the remainder of the day.

Increased cage size does not alter heart rate or behavior in female rhesus monkeys

The behavioral and heart rate responses of 10 female rhesus monekys to three different-sized, barren cages were measured. No differences were found and the conclusion drawn that the proposed [by USDA, 1985] changes in cage size will not improve well-being...

Preliminary comments on resocialization of aged macaques

Group formation technique is described. Each rhesus monkey [6 males and 7 females] was introduced to group members in a series of brief pair tests. Despite the number of injuries, and the death of one monkey, we view the resocialization...

Behavioral responses of female long-tailed macaques (Macaca fascicularis) to pair formation

Pair formation technique is described. Five of six pairs tested were compatible during a five to six months study period. Self-abusive behaviors were recorded for five of the ten subjects when singly housed, but were completely absent after pair formation....
