An orangutan exhibit at the Sedgwick County Zoo is studied for the purpose of examining the social behavior of orangutans in a captive environment. Specific reference is made to the patterns of use of various movable and immovable structures and specific locations displayed by the occupants of the exhibit. Patterns of individual preferences and utilization of the exhibit are also discussed, illustrating the spatial and structural needs of individual orangutans. The results are hoped to further our understanding of the need for improved facilities for captive orangutans as social groups and as individuals.
