Rare cirl buntings see 33% population boost on National Trust farmland in Devon
Sixty breeding pairs of the rare cirl bunting have been recorded between Bolt Head and Bolberry Down on land owned by the National Trust in the South Hams. The 33% increase to sixty pairs, from forty in previous years, is the highest count of the small birds in the area since recording began in 2012. The area is one of the most important sites for cirl buntings in the UK, which are currently classified as red conservation status.
The National Trust has worked to improve habitat and food sources for the birds by making small changes to farm animal grazing patterns along the coastline. A mixture of sheep grazing during the winter and low-level cattle grazing in the summer months has helped to create a rich grassland abundant with wildflowers. This has helped to improve habitats for cirl buntings, but also the insects and native seeds they eat.
The Trust worked with farm tenants in the area and the RSPB, and it’s hoped that the increase in available food sources and habitat for the birds will help maintain the larger population of sixty pairs.
Emma Reece, Area Ranger for the National Trust in South Devon said: “We’re really pleased to see this boost in numbers this year. Our hope is that the work we’ve done will help to sustain the breeding pairs at this higher number for many years to come.”
She continued: “A simple tweak to how we work with the grazing animals used has made this positive change. We plan to do more nature-friendly farming in the area which we hope will help sustain the cirl buntings. This will include allowing a mix of grazing techniques and allowing the borders around fields to grow, providing a variety of food sources for birds, bees and butterflies. We know it might look a little untidy, but this vital mix of long grasses and wildflowers is just what nature likes and needs to flourish.”
Patches of scrubby gorse, blackthorn and thick hedgerows have been created, which help to provide nesting sites and cover on the exposed coastal farmlands. The birds also need well managed grasslands full of wildflowers so there are lots of insects, such as grasshoppers, to feed on through the spring and summer when they are breeding. In winter they feed on seeds dropped from cereal harvest. Leaving large areas of stubble for them to forage helps provide access to this important food source for cirl buntings, and overwintering skylarks have also been seen benefitting too. The Trust have also recently completed an extra kilometre of new hedgerow at Southdown Farm to provide more habitat and shelter for wildlife.
The cirl bunting has been monitored closely by a local ornithologist, Rob Macklin, for the past six years. He noted that numbers have been healthy and stable at around forty breeding pairs, however this year has seen a record sixty pairs breeding through three National Trust farms between Salcombe and Hope Cove in South Devon.
Rob said: “This year sixty pairs of cirl buntings were recorded on National Trust land between Bolt Head and Bolberry Down in the South Hams, the highest count since recording began in 2012. This area is one of the most important sites for cirl buntings in the UK. Recent work by the National Trust to improve the habitat requirements for this iconic species, including the provision of winter feeding opportunities by creating areas of wild bird food and leaving overwintering stubbles, should ensure that this nationally important population continues to thrive.”
Work has been going on through South Devon to improve habitat for cirl buntings since the 1990’s when their numbers declined to only 118 pairs nationally in 1989 and the RSPB launched a successful project to improve their habitat.
