Linnets are farmland finches that have declined severely with agricultural intensification, their welfare depending on seed-rich habitats and low-growing scrub for nesting.
Linnet welfare in winter is critically dependent on seed food availability. Loss of arable weeds from herbicide use and autumn sowing has removed the winter seed resource base. Individual birds in seed-depleted landscapes face chronic energy deficit through January to March. Breeding season welfare depends on insect availability in margins and nesting cover. Agri-environment seed mixes directly address the most critical welfare limitation by providing reliable winter food. Farming practice changes have been the primary driver of welfare decline and are the key to recovery.
