The Royal Society for the Protection of Birds has issued an urgent warning for gardeners to stop leaving seeds and peanuts out for birds during the summer months, including July. New rules took effect on May 1 and will remain in place until October 31, aiming to curb the spread of a deadly disease.
Why the Ban on Seeds and Peanuts?
The RSPB advises against feeding birds seeds or peanuts from May 1 to October 31 due to concerns about trichomonosis, a highly contagious disease that spreads where birds gather in large numbers, such as at bird feeders. While well-meaning, this practice is actively spreading the illness among garden birds.
Decline in Greenfinch Populations
The charity points to evidence that greenfinch numbers have collapsed by 65% since 1979. According to the RSPB, “Greenfinches, for example, have dropped by over 65% in the last three decades – and you may have seen this decline yourself. Back when the Big Garden Birdwatch started in 1979, Greenfinches were at number seven in the top ten birds seen. This year they were down to number 18.”
Safe Feeding Alternatives
The RSPB stresses that small amounts of suet, fatballs, or mealworms are acceptable during this period. The charity emphasizes seasonal and safe feeding practices to avoid disease spread.
Additional Recommendations
The RSPB advises cleaning and moving feeders weekly, changing water in bird baths daily, and avoiding flat-surfaced feeders such as bird tables. Last year, the RSPB banned the sale of flat bird feeders pending further investigation due to concerns they could spread the disease.
The RSPB stated: “Stopping the spread of disease is a challenge we can’t tackle alone. By taking these simple steps to feed seasonally and safely, we can all help protect the future of our birds.”
