This document discusses animal behavior in captivity and ways to address abnormal behaviors that often develop. It notes that captive environments are static with regimented care and little interaction, unlike natural environments. As a result, many animals display stereotypic or abnormal repetitive behaviors like pacing and feather plucking. While drugs are commonly used in zoos to treat these behaviors, enrichment is a better approach to improving psychological health by making environments more stimulating. The document promotes an upcoming talk on creating enrichment devices from recycled materials to enhance captive animal welfare.
