Behavioral effects of changing group membership among captive lowland gorillas

After visual and limited-contact familiarization new members were introduced to an existing group. Seven adult females were moved among four breeding groups. The order in which new members were introduced was determined by knowledge that the zoo staff had of...

Space requirement stipulations for caged non-human primates in the United States: A critical review

Cage space requirements for non-human primates in the United States of America are less than those in European countries. Studies in support of the assumption that the US legal minimum cage size provides adequate space have limited value because they...

Managing an all-male group of gorillas: Eight years of experience at the St. Louis Zoological Park

Our experience suggests that a gorilla bachelor group is a viable and indeed a desirable alternative to solitary housing of 'emigrated' captive males.

Influence of availability of perches on the behavioral well-being of captive, group-living mangabeys

A total deprivation of perches yielded an increase in aggressive behaviors and locomotion, and a decrease in cohesiveness. Placing perches progressively in the experimental cage restored the level of all the variables to levels found in the control cage [with...

Training as enrichment

Training may be the best management tool an animal care giver can use. In 1989 the Brookfield Zoo in Chicago started training their orangutans to accept insulin injections using operant conditioning and target training techniques. They have also taught these...

What makes novel objects enriching? A comparison of the qualities of control and complexity

The overall picture from this experiment is that [group-housed] captive monkeys prefer responsive objects to unresponsive ones but have no preference for visual complexity over simplicity.

Effects of straw bedding on non-social and abnormal behavior of captive lowland gorillas (Gorilla gorilla gorilla)

Two individuals were frequently observed to hold their ears or head while the exhibit was in an unbedded condition. This behavior virtually disappeared in the enriched condition. ... Of the eight individuals found to engage in coprophagy, five individuals were...
