Meeting the social space requirements of pair-housed primates

Social space is the space required by a subordinate partner to buffer potential social tension, by increasing the distance to a dominant counterpart. At a minimum, pair-housed animals should be allocated at least twice the cage space that is legally...

Maracas for Macaca? Evaluation of three potential enrichment objects in two species of zoo-housed macaques

One group each of Barbary macaques and stump-tailed macaques, both zoo-housed, received hard replica fruits in three experimental conditions: as empty (unresponsive) objects, as maracas that rattled when manipulated (simple responsive), and as objects from which food items could be...

Behavioral intervention program: Enriching the lives of captive nonhuman primates

Since its inception, 142 animals have been reported to the BIP [Behavioral Intervention Program, developed in 1994], including chimpanzees, baboons and other monkeys. The most common behaviors reported were hair pulling, pacing, rocking and self-aggression. 36.6% of the BIP subjects...

Observations on the behavior of gibbons (Hylobates leucogenys, H. gabriellae, and H. lar) in the presence of mirrors.

Three captive gibbons (Hylobates leucogenys, H. gabriellae, and H. lar) were videotaped in the course of longitudinal exposure to mirrors introduced into their familiar cage or island housing situation. The gibbons, which differed in age, sex, species, and rearing condition,...

Physiological correlates of self-injurious behavior in captive, socially-reared rhesus monkeys

This study examined the relationship between self-injurious behavior (SIB) in rhesus monkeys and several biological variables, including monoamine metabolites in cerebrospinal fluid (CSF) and circulating levels of ACTH, cortisol, and testosterone. Cisternal CSF and blood plasma samples were obtained from...
