Red-backed shrikes have declined dramatically across northern and central Europe, with welfare challenges from loss of insect-rich scrub habitats and changes in traditional low-intensity farming.
Red-backed shrike welfare is directly linked to the mosaic of scrub and open habitat that intensive farming has largely eliminated. Without thorny scrub for nesting, pairs cannot establish breeding territories. Without abundant large insects (beetles, grasshoppers, small vertebrates), adults cannot provision chicks adequately. The species characteristic behaviour of impaling prey items (a food larder) reflects high prey specialisation — reduced prey abundance forces adults to forage over larger areas, reducing time brooding chicks. Agri-environment schemes that restore scrub mosaics and reduce pesticide use directly improve welfare conditions.
