Supplemental feeding of wild birds is one of the most widespread human-wildlife interactions, with both welfare benefits and risks that are rarely understood.
Wild bird feeding sits at an interesting welfare intersection. It provides genuine nutritional support, especially during cold snaps, and brings people into caring relationships with wildlife. But poorly maintained feeders spread disease, and inappropriate food causes harm. The welfare-positive approach is not to stop feeding but to feed responsibly: clean feeders regularly, use appropriate food, position feeders safely.
