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...

Male pigtailed macaques neonatally separated from mothers for clinical reasons show increased abnormal behavior as adults

The proportion of the first 48 months of life spent singly housed was significantly related to abnormal behavior in maturity. It explained 12% of abnormal behavior in mother-reared animals, 42% in experimental-nursery-reared animals, and 55% in clinical-nursery-reared animals.

Training multi-task medical behaviors in the bonobo (Pan paniscus)

The bonobo training program at the Milwaukee County Zoo (MCZ) began in 1993. Currently, the bonobos voluntarily participate in medical behaviors that involve performing several tasks simultaneously. To date, we have compiled three complete sets of obstetrical ultrasound measurements, have...
