Garden bird feeding provides genuine welfare benefits when done correctly, but incorrect food and hygiene failures can cause serious disease that outweighs the benefit.
Garden bird feeding is one of the most direct and accessible welfare contributions available to individuals — but like any welfare intervention, doing it badly can cause more harm than good. Dirty feeders spread Trichomonosis and salmonella; inappropriate food (bread, milk) causes nutritional deficiencies; loose peanuts during nesting season can choke chicks. The welfare benefit of feeding is maximised by providing species-appropriate food in clean, regularly maintained feeders, positioning feeders to minimise cat ambush risk, and providing water for drinking and bathing alongside food. Done well, garden bird feeding genuinely supports populations through food-scarce periods.
