Wild Bird Garden Feeding: Best Practice for Winter

Winter garden bird feeding provides significant welfare benefits for garden bird populations, but best practice hygiene and food choice are essential to avoid disease and harm.

Key Facts

Garden bird feeding in winter increases survival rates for some species during cold snaps
Feeders should be cleaned at least every two weeks with hot soapy water and a disinfectant rinse
Avian trichomonosis (caused by Trichomonas gallinae) is spread via contaminated feeders
Black sunflower seeds, nyjer seeds and fat balls (without netting) are high-value foods
Ground feeders for robin, dunnock and blackbird should be in separate locations from hanging feeders

Welfare Considerations

Garden feeding, when done hygienically, provides real welfare benefits to species that struggle to find food in cold or dry weather. However, poorly maintained feeders become disease transmission hotspots, particularly for finches (trichomonosis) and greenfinches (salmonellosis). The welfare benefit of feeding is conditional on the commitment to regular cleaning and hygiene maintenance.

What You Can Do

Clean feeders and bird baths at least twice monthly, more often in warm weather
Remove old or mouldy food promptly to prevent disease
Offer a variety of food types to support different species
Provide fresh clean water alongside food - this is often more beneficial than food alone
