Stereotypic behaviors and behavioral abnormalities in zoo animals are welfare indicators requiring systematic assessment and management response, with their prevalence providing insight into the welfare quality of captive environments.
Behavioral abnormalities in zoo animals provide direct evidence of welfare compromise that zoos cannot ignore when committed to evidence-based welfare improvement. High stereotypy prevalence indicates that captive conditions are not meeting behavioral needs, regardless of how well other welfare aspects are managed. Systematic behavioral assessment enables comparison between facilities and management approaches, identifying welfare-positive practices that can be shared across the zoo community. The obligation created by welfare monitoring findings is to implement management changes that reduce abnormal behavior prevalence, not simply to document and accept poor welfare outcomes.
