One of Britain’s most threatened birds, the stone-curlew, has seen a rise in population numbers in Wessex and the Brecks thanks to the work of the RSPB in collaboration with farmers, landowners and other partners across farmland, grassland and heathland habitats.
Numbers of the bird counted across the project area alone have now more than doubled since a nationwide population low in the 1980s.
Celebrating their 40th anniversary this year, two stone-curlew projects have been working in partnership with farmers, landowners and gamekeepers across Wiltshire, Hampshire, Berkshire, Oxfordshire, Norfolk, Suffolk and Cambridgeshire to provide suitable habitat, including nesting sites, for these wide-eyed rare birds.
Migrating to our shores from southern Spain and northern Africa to raise their young each year, these peculiar-looking birds are crow-sized, have long yellow legs and – perhaps most distinctively – golden orb-like eyes which enable them to find food under the cover of darkness.
Once found widely throughout England, from Dorset to Yorkshire, stone-curlew numbers declined through the 19th and early 20th century with 1,000 to 2,000 pairs remaining by the 1930s. Their numbers and range continued to shrink dramatically, with fewer than 150 pairs found nationwide by 1985, with their rapid decline a result of agricultural change and loss and deterioration of their breeding habitats.
Now, after 40 years of dedicated conservation from the RSPB, farmers and other landowners, the stone-curlew population has more than doubled, with nearly 350 breeding pairs nationally (including estimates for un-monitored sites).
The collaborative efforts to achieve this success have been no mean feat however, as the small population is highly vulnerable to change. The species is particularly sensitive to unseasonal and extreme weather variations, including an unseasonably cold snap in 2013 which sadly caused approximately 20 per cent of the Stone-curlew population to perish in late spring.
Reflecting on the rise in the stone-curlew population, Tim Cowan, RSPB Conservation Officer said, “The willingness of farmers and landowners to work with the projects and our dedicated volunteers by creating and protecting stone-curlew breeding sites over the past four decades, has been remarkable.”
Stone-curlew are very specific about where they nest, preferring light, free-draining soils, such as chalk downland, sandy heaths and farmland. Over the years, suitable downland and heathland sites across their key breeding grounds have become limited, while nests and chicks are also vulnerable as a result of mechanised farming practices and reduced invertebrate foodstuffs due to increased pesticide usage and habitat change.
Despite these pressures, farmers and landowners have been critical to the recovery of the species, working together with the RSPB and other partners to create nesting plots within arable land for stone-curlew breeding which ensure that eggs and chicks are safe from operations. Alongside this, a team of dedicated RSPB volunteers annually monitor nest sites and support farmers in the development and implementation of nature-friendly measures across farmland to help support Stone-curlew and other wildlife.
Tim, a farmer in Norfolk who is participating in the project, said, “For over 30 years, our farm has proudly collaborated with the RSPB to create and enhance vital breeding habitats for the stone-curlew. Through dedicated stewardship schemes, we have worked together to ensure this rare and vulnerable species has the best possible conditions to thrive on our land.
“Our partnership work has been built on a shared commitment to balancing productive farming with wildlife conservation. By integrating conservation-focussed farming practices, we have not only contributed to the recovery of the stone-curlew but have also fostered a healthier ecosystem locally.
“The success of this project is a testament to the power of partnerships in conservation and demonstrates how farmers and conservation organisations can work hand in hand to protect and enhance biodiversity in the UK.”
