Households feeding birds in the UK are being urged to modify their practices to combat the spread of trichomonosis, a disease that has significantly impacted Greenfinch populations, which have declined by 67%, leading to their placement on the UK Red List. The Royal Society for the Protection of Birds (RSPB) recommends that from May 1 to October 31, bird feeders should not include peanuts and seeds, as these can facilitate the spread of the disease during warmer months. Instead, bird enthusiasts are encouraged to provide small amounts of mealworms, fat balls, or suet throughout the year. RSPB Chief Executive Beccy Speight emphasized the importance of feeding birds in a way that supports their long-term health, urging regular cleaning of feeders and relocating them to prevent contamination. By implementing these changes, the public can continue to enjoy bird feeding while protecting vulnerable species.
