Feeding garden birds is one of life’s simple pleasures, and new research is helping us understand how to make this much-loved activity even safer for the wildlife we love.

A recent evidence review led by the RSPB has highlighted that while feeding birds can be beneficial, it can also increase the spread of disease. One such disease, trichomonosis, has contributed to significant declines in species like greenfinch and chaffinch.

Simple changes can make a real difference. Updated guidance encourages us to feed birds seasonally. During the warmer months (May to October), birds have access to plenty of natural food and the risk of disease transmission is higher. During this time, it is best to pause offering seeds and peanuts, which tend to attract larger numbers of birds into close contact. Instead, small amounts of mealworms, suet or fat balls can be offered in moderation. Then as natural food becomes scarcer in the colder months (November to April), feeding seeds and peanuts can recommence.

Hygiene is just as important. Hanging feeders are now recommended over flat surfaces like bird tables, which can see contaminated food build up. Regularly clean and move feeders to stop debris accumulating. Change water daily and clean birdbaths weekly. If you notice a bird that appears unwell, take a short break from feeding and thoroughly clean equipment to help stop any disease spreading.

Create natural food sources too. Plant berry-rich shrubs, leave areas a little wilder and encourage insects to ensure a varied, nutritious diet all year round.
