While the house sparrow has taken the top spot for the most frequently recorded bird across the UK, Surrey is defying the national trend. According to the latest findings from the Royal Society for the Protection of Birds (RSPB), the blue tit has emerged as the most common species spotted within the county.
Local Trends vs. National Data
The RSPB’s annual Big Garden Birdwatch —a long-standing survey conducted since the late 1970s—provides a vital snapshot of avian populations. Nationally, the study identified the house sparrow, blue tit, and starling as the three most common birds.
However, Surrey’s local ecosystem shows a different hierarchy:
– Surrey: The blue tit leads, followed by the wood pigeon and the house sparrow.
– Kent and West Sussex: The house sparrow, blue tit, and starling hold the top positions.
– East Sussex: The house sparrow, blue tit, and wood pigeon are the most frequent visitors.
These variations highlight how local environments and habitats can create distinct patterns in bird populations, even within relatively close geographic areas.
A Critical Warning: The Threat of Trichomonosis
Alongside these population insights, the RSPB has issued a timely plea to the public regarding garden bird feeding. To protect vulnerable species, the charity is advising gardeners not to provide seeds or nuts between May and the end of October.
The primary reason for this restriction is the spread of Trichomonosis, a parasitic disease that targets the mouths, throats, and upper digestive tracts of birds.
Why this matters for bird health:
- Physical Impact: The parasite makes it increasingly difficult for birds to eat, drink, or breathe.
- Targeted Species: While it affects various birds, it is particularly devastating to greenfinches and chaffinches.
- Population Decline: Long-term data from the Big Garden Birdwatch shows a substantial decline in both song thrush and greenfinch numbers, a trend that conservationists are monitoring closely.
How Gardeners Can Help
To mitigate the spread of disease and support conservation efforts, the RSPB recommends two specific actions for bird enthusiasts:
- Pause Feeding: Avoid putting out seeds and nuts during the summer months to help stem the spread of the parasite.
- Maintain Clean Water: If you provide water for birds, especially during hot weather, change it daily. The disease can persist in standing water, making fresh, clean sources essential for survival.
“That gives us important information about the conservation that we need to carry out,” stated RSPB spokesperson Martin Fowlee, emphasizing the value of these citizen-science observations.
Conclusion
While Surrey’s blue tit populations remain robust, the RSPB warns that seasonal feeding habits could inadvertently spread Trichomonosis. By adjusting feeding and watering practices during the summer, gardeners can play a vital role in protecting declining species like the greenfinch.
