Corn buntings have declined catastrophically on UK farmland and their welfare is tied to traditional mixed farming landscapes with winter stubbles and beetle banks.
Corn bunting welfare in winter is critically dependent on seed food availability. Loss of spring-sown cereals and overwinter stubbles removed the seed resource base that supported large populations. Individual birds in landscapes with only autumn-sown crops face chronic food shortage through January to March. Breeding season welfare depends on invertebrate availability for chick rearing in field margins. Emergency agri-environment interventions providing winter seed mixes and spring-sown plots directly address the most critical welfare limitations.
