Stone Curlew Welfare and Conservation in the UK
Species Overview
The stone curlew (Burhinus oedicnemus) is a migratory wader that breeds on open stony ground, chalk downland, and arable farmland in southern England. It winters in Africa. With only around 400 pairs in the UK, it is a Schedule 1 species afforded legal protection. Its cryptic plumage and crepuscular/nocturnal habits make it difficult to observe but vulnerable to disturbance.
Habitat Requirements
Stone curlews require open, sparse vegetation habitats: short chalk grassland, Breckland heath, and open arable fields with bare soil. Nest sites must have good visibility to detect predators. Loss of chalk downland and changes in arable management (earlier crop growth covering bare soil) have reduced available habitat. The RSPB and Natural England work with farmers through agri-environment schemes to provide suitable nesting areas.
Breeding Welfare Challenges
Stone curlews lay eggs directly on the ground, making nests highly vulnerable. Agricultural operations (ploughing, rolling, spraying) can destroy eggs or chicks. Nests are marked and protected by farmers participating in conservation schemes. Predation by foxes and corvids is a significant chick mortality cause. Human disturbance causes nest abandonment.
Migration and Wintering
Young birds make their first migration to the Sahel and West Africa. Migration is hazardous: artificial lighting, vehicles, and changed habitats along routes pose risks. Climate changes are altering the timing of migration and habitat conditions on wintering grounds. Poor conditions on passage or wintering grounds reduce survival and subsequent breeding success.
Conservation Success and Future
Stone curlew numbers have recovered from a low of around 150 pairs in the 1980s to over 400 pairs today, largely thanks to targeted conservation action including nest protection, agri-environment schemes, and captive rearing/release programmes at some sites. Continued collaboration between farmers, conservation bodies, and government agencies is essential. Maintaining this success requires long-term commitment to habitat management and monitoring.
