The problem of foraging in captive callitrichid primates: Behavioral time budgets and foraging skills

The group-housed animals had to hang from above, or sit on the covered bowl to obtain raisins that were mixed with ground corn cob. The device reduced foraging yield and increased foraging effort to levels similar to those observed in...

Functions and social consequences of infant-adult male interaction in a captive group of lowland gorillas (Gorilla gorilla gorilla)

Males expressed interest in and care giving toward the infant and used her as an object in excited display, and one male used her to tease her mother. The infant expressed interest in care seeking toward one male. Males interacted...

Environmental influences on reproduction and maternal behavior in captive gorillas: Results of a survey

There are factors in the physical environment that appear to influence tendency of mothers to abuse or neglect their infants. ... Opportunities for activity and play reduce stress and boredom, as do refuges for privacy. ... Generally, it seems that...

Modification of stereotypic behavior in rhesus monkeys using videotapes, puzzlefeeders, and foraging boxes

Results of this study demonstrate that foraging boxes and puzzle feeders can reduce stereotypic behavior significantly [in single-housed subjects]. Audiovisual stimuli through videotapes were also useful environmental tools; however, some stereotypic behavior continued.

Primatology and primate well-being

Rather than fostering a climate of intelligent inquiry and lovely concern, the effect of the proposed rules will be oppressive and inhibitory. They will reduce individual discretion and institutional flexibility in the care of captive primates.

Primate research models and environmental enrichment

An apparatus that the monkey can control, and that responds to the monkey in some way, will be used by a larger proportion of animals, and for a longer period of time, than devices or toys that are not actively...

Uprooted trees facilitate the psychological well-being of captive chimpanzees

Group-housed subjects used the tree during 41.9% of the data points collected during the first day trees were introduced. Thereafter, the mean for trees use dropped to 3.5% and remained fairly consistent.

Food puzzle device simulating termite fishing for captive chimpanzees (Pan troglodytes)

Significant reductions of abnormal behavior and significant increases in activity occurred with the pipe feeder's availability. Species-typical tool-using activity occurred, and the use of the pipe feeder increased subjects' foraging and feeding activity toward more species-normative levels. In the corral-housed...

Influence of cage size on heart rate and behavior in rhesus monkeys

In single-housed subjects there were no significant differences in basal heart rates or activity counts as a function of cage size [of barren, single cages].

Adult female rhesus macaques responded with a significant, protracted increase in heart rate to being placed in transfer boxes while their dirty cages were replaced with clean ones. The mean heart rate remained elevated for two hours after completion of...
