Intentional feeding of wild animals is widespread but raises genuine welfare and ecological questions. Evidence-based guidelines can maximise welfare benefits while minimising harm.
Wild animal feeding sits on a spectrum from clearly beneficial — targeted supplementary feeding of threatened populations in harsh conditions — to clearly harmful — creating food dependency that disrupts natural behaviour and concentrates disease risk. The welfare principle that guides responsible feeding is additionality without dependency: providing food that supplements natural sources during scarcity without replacing them or creating behavioural changes that persist when feeding stops. For garden birds, the evidence is generally positive when correct foods and clean feeders are used. For mammals, the welfare calculus is more complex and species-specific. The most welfare-harmful feeding scenarios involve large animals that become habituated to human presence, lose natural foraging behaviour, and then face acute welfare stress when feeding stops.
