The corncrake - once a familiar rasping voice of hay meadows across Britain - is now confined to a few strongholds in the Scottish islands and Ireland, with recovery depending on sympathetic farming.
The corncrake's near-extinction from mainland Britain is a historical welfare catastrophe caused by a single technological change - the adoption of mechanical hay cutting. Individual birds and their chicks were killed in large numbers each season. Conservation recovery requires not just reintroduction but sustained changes to farming practice that allow breeding success each year. Where sympathetic management is practised, corncrakes can breed successfully - proof that the welfare deficit is addressable through informed land management.
