The Eurasian curlew is one of the UK's most threatened breeding birds. Chick survival on farmland depends on habitat structure, predator pressure, and agricultural management during the breeding season.
Curlew chick welfare depends critically on surviving the first five weeks before fledging. Chicks are mobile but vulnerable, depending on parental vigilance and adequate insect food. Silage cutting before chicks can fly results in death by cutting machinery or predator exposure in the short vegetation aftermath. Predator pressure creates chronic stress for brooding adults. The combination of agricultural intensification and high predation creates a welfare trap for individual birds and a population-level crisis.
