Eurasian curlews are critically threatened in the UK, and protecting their ground nests from predation and agricultural disturbance is vital for population recovery.
Curlew welfare during the breeding season centres on the stress of repeated nest failure, which is now almost universal in many lowland sites without conservation intervention. Nest loss due to predation, agricultural machinery, and human disturbance causes acute stress responses in adults and death of eggs and chicks. Each failed attempt requires renewed energy investment in re-nesting. Adults that fail repeatedly across seasons experience chronic reproductive stress alongside declining physical condition. Nest protection schemes that combine predator management and farmer engagement significantly improve breeding success.
