As the summer months approach, the Royal Society for the Protection of Birds (RSPB) is calling on enthusiasts to modify their bird-feeding habits to curb the spread of avian diseases, particularly trichomonosis. The charity emphasises that while feeding birds is a cherished activity for many, it is essential to do so in a manner that prioritises the health of vulnerable species.
The Call to Action
With the warmer weather on the horizon, the RSPB is advising the removal of seed and nut feeders from gardens starting 1 May and continuing through to 31 October. This recommendation is driven by concerns over the health of birds such as the greenfinch, which has seen a staggering 67% decline since the RSPB’s annual Big Garden Birdwatch began in 1979. The charity’s guidance aims to minimise gatherings of birds around feeders, where the risk of disease transmission is heightened.
Beccy Speight, the RSPB’s chief executive, articulated the urgency of the situation: “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.”
Understanding Trichomonosis
Trichomonosis is a parasitic infection that primarily threatens finch species and is easily transmitted through saliva at feeders. During the hotter months, the parasite can persist in the environment longer, facilitating its spread among bird populations. The RSPB reports that an estimated 6 million greenfinches and chaffinches have succumbed to this illness in recent years.
To mitigate these risks, the RSPB suggests offering alternative foods that do not attract large flocks. Suitable options include small quantities of mealworms, fat balls, or suet, which provide necessary protein for breeding birds without encouraging extensive congregations.
Recommendations for Feeding Practices
During the summer months, the RSPB recommends the following guidelines to ensure safe feeding:
– **Remove seed and nut feeders**: These attract larger numbers of birds, increasing the chances of disease spread.
– **Opt for protein-rich foods**: Mealworms or fat balls can be offered in moderation as these do not draw in large flocks.
– **Maintain cleanliness**: Regularly clean and reposition feeders every week, and ensure that any water provided is changed daily to reduce contamination risks.
In addition to these practices, the RSPB encourages plantings that support birdlife, such as sunflowers and teasels, which not only provide natural food sources but also help foster the insect populations essential for feeding chicks.
The Big Garden Birdwatch Insights
The RSPB’s annual Big Garden Birdwatch, which attracts around 650,000 participants, has revealed alarming trends in bird populations. In the latest survey, the house sparrow retained its top position as the most frequently seen bird, while the greenfinch dropped to 18th place, underscoring the urgent need for conservation efforts. The data highlights a broader picture: while some species, such as the wood pigeon, have seen population increases, many others, including the starling and greenfinch, face severe declines.
Top 5 Birds from the Big Garden Birdwatch 2026:
1. **House Sparrow**: Average of 3.57 per garden; present in 57.1% of gardens.
2. **Blue Tit**: Average of 3.12 per garden; seen in 78.5% of gardens.
3. **Starling**: Average of 2.23 per garden; present in 31.4% of gardens.
4. **Wood Pigeon**: Average of 2.21 per garden; found in 75.2% of gardens.
5. **Blackbird**: Average of 1.68 per garden; spotted in 71.7% of gardens.
Why it Matters
The RSPB’s recommendations come at a critical time for British wildlife, as the health of bird populations directly reflects the overall state of the environment. By adjusting feeding practices, individuals can play a vital role in protecting avian species at risk. The decline of the greenfinch and other birds highlights the interconnectedness of our ecosystems, where even small changes in behaviour can lead to significant improvements in biodiversity. Ensuring the well-being of garden birds is not only a matter of conservation; it is a reflection of our commitment to nurturing the natural world around us.
