The reed bunting has expanded from its traditional reedbed habitats into farmland but has declined overall, and welfare depends on seed-rich arable habitats in winter and dense marsh vegetation for breeding.
Reed bunting welfare is threatened by loss of both wetland breeding habitat and seed-rich farmland for winter food. The species colonisation of arable land made it vulnerable to changes in farming practice including loss of winter stubbles. Garden feeding and wetland restoration both contribute to welfare improvement.
