How ethical frameworks govern zoo behavioral research and what good practice looks like for research on captive animals.
Ethical zoo research requires a framework that takes seriously the welfare costs of research participation by animals who cannot consent. Non-invasive research — behavioural observation, cognitive testing, camera-trap study — represents the welfare ideal: valuable scientific knowledge gained without significant cost to individual animal welfare. When research involves handling, immobilisation, or other more invasive procedures, the ethical justification must be proportionate to the welfare cost. The welfare of zoo animals used in research is not simply an ethical constraint on knowledge generation but an integral consideration that shapes which questions can be asked and how. Institutions that approach zoo research this way produce both better science and better animal welfare.
