Urban Wildlife Feeding: Benefits, Harms, and Best Practice

Feeding urban wildlife is a popular activity, but without care it can cause significant harm to the animals it is intended to help.

Key Facts

Millions of people feed garden birds, hedgehogs, foxes, ducks, and squirrels in urban areas
Inappropriate food causes nutritional deficiencies — bread for ducks is a well-documented example
Supplementary feeding can increase local population densities beyond carrying capacity
Disease transmission is elevated at feeding stations where animals congregate in close contact
Dependency on human food sources may reduce natural foraging skills in some species
Feeding stations for garden birds can reduce winter mortality by up to 50% in some studies

Welfare Considerations

Urban wildlife feeding exists on a spectrum from highly beneficial to actively harmful, depending on what is fed, how it is provided, and in what quantities. High-quality supplementary food for garden birds during cold weather clearly benefits individual welfare and population survival. However, feeding bread to waterfowl causes angel wing deformity in ducklings and nutritional deficiencies in adults. Feeding foxes or hedgehogs at predictable locations concentrates animals in ways that facilitate disease transmission. Food provision that eliminates natural foraging behavior may reduce individual fitness over time. The welfare-positive approach involves species-appropriate food, clean feeding stations, seasonal adjustment, and awareness of population-level effects.

What You Can Do

Feed garden birds species-appropriate food — seeds, fat balls, and suet rather than bread
Keep feeding stations clean and dry to prevent mould and disease transmission
Avoid feeding ducks bread — use defrosted peas, corn, or specialist waterfowl food instead
Provide supplementary hedgehog food (meat-based cat food) in autumn before hibernation
Do not leave food out in ways that habituate foxes to human proximity
