The corncrake has recovered in parts of its UK range through targeted agricultural management. Understanding its ecology helps farmers and conservationists protect this secretive bird.
Agricultural intensification — specifically the shift from late hay cutting to early silage production — caused catastrophic corncrake mortality through nest and chick destruction by mowing machinery. Chicks and incubating adults caught by silage cutters experience traumatic death, while survivors of mowing events are exposed to predators in the open. The welfare harm is both direct — mechanical death — and indirect — loss of habitat causing nest abandonment and chick starvation. Agricultural management that delays cutting and uses escape-route-creating techniques (centre-to-edge cutting) dramatically reduces both individual welfare harm and population-level mortality. Agri-environment scheme payments compensate farmers for the economic cost of delayed cutting.
