Wild Curlew Upland Breeding Welfare

Curlews are experiencing one of Britain's worst bird population declines, with upland breeding populations particularly threatened by predation, habitat degradation, and disturbance. Individual breeding pair welfare is the focus of intensive conservation effort.

Key Facts

UK curlew populations declined by 48% between 1994 and 2015, with upland populations declining faster
Curlews are ground-nesting birds whose nests and chicks are vulnerable to fox, crow, and stoat predation
Predation management at curlew nesting sites can triple breeding success compared to unmanaged sites
Habitat degradation through drainage, overgrazing, and bracken encroachment reduces suitable nesting habitat
Human disturbance from walking, dog walking, and recreational activities causes nest abandonment
The Curlew Country and other projects combine predation management, habitat restoration, and disturbance reduction
Curlews give alarm calls near nests - this behaviour is a sign of disturbance that should prompt withdrawal
Agri-environment scheme options for curlew management include late-cutting grassland and wetland restoration

Welfare Considerations

Curlew breeding welfare depends critically on freedom from nest disturbance and predation. Individual breeding pairs disturbed from nests repeatedly face egg chilling and increased predation risk. The stress of repeated disturbance is real and measurable. Successful breeding requires the sustained commitment of both parent birds over 4-5 weeks of incubation and chick-rearing. Human disturbance that disrupts this investment causes welfare harm as well as conservation damage. Spatial management directing recreation away from nesting areas protects individual breeding pair welfare.

What You Can Do

Keep dogs on leads and avoid moorland areas with curlew nesting signs during April-June
Support Curlew Country, RSPB, and Wildlife Trust curlew conservation projects
Report curlew nesting activity to local bird groups and the BTO to support monitoring
Advocate for agri-environment funding for curlew habitat management and predation control
