The Eurasian curlew is one of Europe's most threatened birds, with UK populations declining over 65% since the 1970s due to agricultural intensification and predation.
Curlew chicks that survive early predation face nutritional stress in degraded grasslands where invertebrate prey has declined. Adult curlews maintain large territories that are increasingly fragmented, increasing energy expenditure and reducing breeding success. The species faces a slow welfare and population crisis.
