Garden bird feeding provides welfare benefits for wild birds when done correctly but can cause harm through disease transmission and inappropriate food if done poorly.
Garden bird feeding done well provides genuine welfare benefits through supplementary nutrition during winter food scarcity and supporting breeding birds with high energy requirements. Done poorly, feeders become disease transmission hubs that create welfare harm. Regular cleaning with hot water and dilute bleach, providing appropriate foods, and positioning feeders safely away from predator hiding spots are essential welfare practices for anyone feeding garden birds.
