Garden bird feeding supports over a billion individual birds annually but can cause harm if done incorrectly — this guide covers evidence-based best practices.
Garden bird feeding done well is genuinely beneficial for wildlife welfare. Done poorly, it can spread disease, attract predators and provide nutritionally inadequate food. Feeders must be cleaned weekly with hot soapy water and rotated regularly to prevent ground contamination. High-quality sunflower hearts, nyjer seed and suet provide good nutritional value. Positioning feeders more than 1 m from windows reduces fatal collision risk.
