Garden bird feeding provides significant welfare benefits to wild birds but must be done responsibly to avoid harm through disease and inappropriate food.
Wild bird feeding, when done responsibly, is among the most accessible and effective ways individuals can improve wildlife welfare. However, poorly maintained feeders become sources of lethal disease outbreaks - greenfinch populations in the UK declined by 35% partly due to trichomonosis spread through contaminated feeders. Providing appropriate, fresh food, cleaning feeders regularly, and placing them safely reduces harm and maximises benefit. The interaction between garden bird feeding and cat predation is also a welfare concern: feeders that concentrate birds in locations accessible to cats increase predation rates. Evidence-based feeding practices transform a well-intentioned activity into a genuinely welfare-positive one.
