The Royal Society for the Protection of Birds (RSPB) has issued new guidance asking UK households to stop leaving seed out for wild birds between May 1 and October 31. During the warmer months of summer and autumn, the risk of disease transmission among birds increases, prompting this seasonal pause in seed feeding.
The RSPB explains that natural food sources—such as seeds and insects—are more abundant during this period, meaning birds do not rely as heavily on supplementary feeding. Instead, they advise that people “pause filling your bird feeders with seeds or peanuts” during these months. However, small amounts of mealworms, fatballs, or suet can still be offered safely.
From November 1 through April 30, households may resume feeding birds a full range of foods, including seeds and peanuts.

To help keep garden birds healthy year-round, the RSPB emphasizes the importance of strict hygiene and feeder maintenance:
-
Clean bird feeders and water baths at least once a week using hot soapy water and a non-toxic disinfectant (such as Ark-Klens or a mild 5% bleach solution). Remove any old food and droppings beneath feeders.
-
Move feeders to a new location weekly to avoid contamination buildup on the ground. If multiple feeders are used, place them in different areas to reduce crowding and interspecies mixing.
-
Avoid positioning feeders beneath roosting sites like trees where droppings accumulate.
-
Refrain from using feeders with flat surfaces (bird tables, window feeders, and tray feeders), as they increase disease risk by collecting contaminated food.
-
Feed in moderation so all food is consumed within one to two days, adjusting amounts based on bird demand to prevent overfeeding.
-
Keep food dry by using feeders that shield against rain and minimize condensation, since damp food encourages disease survival.
-
Change water in bird baths daily, using tap water; a pond provides the best natural water source for birds and wildlife.
The RSPB also encourages gardeners to plant bird-friendly species such as sunflowers, teasels, and ivy, which supply natural food throughout the year and support birds’ long-term wellbeing.
By following these recommendations, bird enthusiasts can help protect wild birds from disease and maintain vibrant populations in their gardens.
