Winter Wild Bird Feeding: Best Practice

Supplementary feeding of wild birds in winter can significantly improve survival rates, but practice matters for both bird welfare and disease prevention.

Key Facts

Supplementary feeding increases winter survival in small songbirds by up to 30%
Garden feeding now sustains populations of some species that would otherwise decline further
Hygiene failures at feeders enable rapid spread of trichomonosis and salmonellosis
Nyjer seed, sunflower hearts, and peanuts provide high energy food for winter birds
Different species require different feeder types to access food effectively

Welfare Considerations

Birds that rely on supplementary feeding during cold snaps can die rapidly if feeders are not maintained. Disease outbreaks at poorly maintained feeders kill birds that would otherwise survive. Responsible supplementary feeding requires regular cleaning, appropriate food types, and positioning feeders to reduce predation risk from cats and sparrowhawks.

What You Can Do

Clean feeders and bird baths every two weeks with a dilute disinfectant solution
Provide a variety of food types in appropriate feeder designs for different species
Remove all food and clean the area thoroughly if you see sick birds at your feeders
Position feeders away from windows to reduce collision risk
Feed consistently through winter as birds come to depend on supplementary food sources
