New guidance for feeding garden birds after annual count

Over 650,000 people took part in the world’s largest garden wildlife survey in January, counting more than nine million birds of over 80 species during this year’s Big Garden Birdwatch – an amazing achievement.

The survey provides a valuable annual snapshot of how our most common garden birds are faring.

Across Yorkshire 49,000 people took part, with the House Sparrow keeping the top spot of the most frequently spotted bird, followed by the Blue Tit and Blackbird in North and West Yorkshire, in East Yorkshire the top three were the House Sparrow, Starling and Blue Tit and in South Yorkshire the top three were the House Sparrow, Blue Tit and Woodpigeon.

However, it is further down the garden rankings where the real story lies. At 18th spot on the list is Greenfinch, which has seen a 67% decline in average numbers recorded since Big Garden Birdwatch began in 1979.

The cause of these losses is disease, especially a disease called trichomonosis, which spreads more easily when birds gather around feeders – particularly in summer and autumn. As a result of these declines, Greenfinches are now on the UK Red List due to disease-related declines.

Despite the risks, feeding garden birds remains hugely beneficial when done safely and at appropriate times of year.

The message is simple: Feed safely. Feed seasonally.

Feed seasonally: It’s important to adjust what we feed our garden birds during the summer and autumn months when there’s a higher risk of disease spreading.

From May 1 to October 31: Pause filling your bird feeders with seed and peanuts to prevent too many birds gathering in one place. It’s okay to keep offering small amounts of mealworms, fat balls, or suet year-round.

Clean and move your feeders weekly: Get into the habit of giving your feeders a good clean at least once a week. If possible, place your feeders in a different spot after each clean to prevent the build-up of contaminated debris underneath. Any existing debris should be cleared up.

Change water daily: Only offer water if you’re able to change it every day and make sure it’s tap water. Water baths should also be cleaned weekly.

Retire flat-surfaced feeders: Research has confirmed that there’s a higher risk of the disease spreading on flat surfaces, where contaminated food can collect for other birds to eat.

The RSPB’s chief executive, Beccy Speight said “Feeding birds is something millions of us love and value, but the science shows us that birds such as Greenfinches have been affected by the spread of disease at feeders.

“We’re not asking people to stop feeding, just to feed in a way that protects birds’ long-term health. By making small changes together, we can ensure garden feeding continues to be a positive force for nature.”
