Wild Bird Garden Feeding - Welfare Benefits and Risks

Garden bird feeding is one of the UK's most popular wildlife activities, providing genuine welfare benefits to millions of birds during harsh weather, but also carrying risks that can be minimized through good practice.

Key Facts

The UK has 60,000 tonnes of bird food put out annually, with approximately 50% of households feeding birds
Supplementary feeding can be critical for bird survival during harsh winter weather and breeding season food shortages
Poorly maintained feeders can spread diseases including trichomonosis, salmonella, and avian pox among birds
Cats kill an estimated 55 million birds in the UK annually, partly concentrated near bird feeders
The evidence base for year-round versus winter-only feeding is still developing, with different species having different needs

Welfare Considerations

Well-managed garden bird feeding provides genuine welfare benefits by supplementing natural food supplies during periods of shortage, particularly during winter cold snaps and spring when insect food for nestlings is scarce. However, poorly maintained feeders concentrate large numbers of birds that facilitate disease transmission, with trichomonosis outbreaks caused by finch feeders killing significant numbers of greenfinches and chaffinches. The welfare calculus of garden feeding requires regular cleaning, appropriate food types, and cat management around feeding stations.

What You Can Do

Clean bird feeders at least every two weeks with dilute disinfectant to prevent disease spread
Provide a variety of food types appropriate to different bird species visiting your garden
Position feeders where cats cannot easily ambush birds, at least 2 meters from dense cover
Report sick or dead birds under feeders to the Garden Wildlife Health Scheme
Continue feeding year-round but use appropriate foods for each season
