Whooper swans migrate annually from Iceland and Scandinavia to winter in Britain, with welfare challenges from habitat loss, lead poisoning, and collision hazards on migration routes.
Whooper swan welfare involves the full annual cycle: breeding in Icelandic uplands, long-distance autumn migration, and winter survival in British wetlands. Lead poisoning from fishing weights causes progressive neurological damage and a slow, distressing death. Power line collisions cause traumatic injury. Habitat loss at key wetland wintering sites reduces food availability during the critical winter energy budget period. Conservation and welfare align directly — protecting wintering habitat and eliminating lead from waterways benefits individual swan welfare immediately.
