Wild Bird Feeding Best Practices

Garden bird feeding provides welfare benefits but requires good hygiene practices to prevent disease transmission.

Key Facts

Garden bird feeding supports over 1 billion birds through food insecurity periods
Trichomonosis spread at feeders has killed millions of greenfinches and chaffinches
Salmonella outbreaks at feeders cause significant songbird mortality
Regular cleaning reduces disease transmission significantly

Welfare Considerations

Bird feeders that are not cleaned regularly become sources of disease that can devastate local populations. Trichomonosis causes a painful throat lesion preventing swallowing. Salmonellosis causes rapid systemic illness. The welfare benefit of supplementary feeding during food-scarce periods is real, but requires good hygiene practice. Poorly managed feeders cause net harm to bird populations.

What You Can Do

Clean bird feeders every two weeks with mild disinfectant
Remove uneaten food before it spoils
Place feeders at different heights to reduce crowding
Stop feeding temporarily if sick birds are seen until the feeder is thoroughly cleaned
