The curlew is Englands most urgent bird conservation priority. Breeding numbers have declined 50% in 25 years, with welfare implications for surviving birds managing in degraded habitats.
Curlew welfare is compromised both at an individual level through failed breeding attempts requiring repeat nesting, and at the population level through inadequate recruitment replacing adults. Repeated nest failures exhaust breeding adults, reducing body condition through extended incubation and the energy cost of relaying. Habitat management creating nest sites with good visibility and reduced mammalian predator pressure through legal control and habitat complexity is demonstrating improved breeding success in trial areas.
