Modern zoo design increasingly incorporates animal agency — giving animals meaningful choices in their environment. This approach produces better welfare and more natural behavior.
Agency-centered zoo design represents a significant advance in welfare philosophy. Traditional zoo design prioritized visitor experience — maximum visibility of animals at optimal times. Animal-centered design asks instead: what choices can we give animals, and how can the environment respond to their choices? Practical implementations include off-exhibit spaces animals can access when they prefer privacy, environmental features animals can manipulate to create preferred microclimates, feeding systems that deliver food when animals perform specific behaviors they enjoy, and exhibit connectivity that allows animals to choose their social environment. This approach produces animals that are more behaviorally active, less stereotypic, and whose welfare is genuinely improved by the environment rather than merely not obviously compromised.
