How camera trap technology improves wild animal welfare research without disturbing individual animals.
Camera trap technology represents an important advance in welfare research methodology because it allows observation of natural behavior without the observer effects that change what is being measured. Wild animals behaving naturally in front of camera traps reveal their actual welfare states through activity budgets, social behavior, and physical condition in ways that direct human observation or capture for assessment cannot achieve. The technology is enabling welfare science to study wild populations at unprecedented scale and without the welfare costs of the more invasive methods it replaces.
