Cranes are among the world's most imperilled birds, with 11 of 15 species threatened or endangered. Their welfare is shaped by habitat loss along migration routes, hunting pressure, and collision with power infrastructure.
Cranes face welfare harms throughout their annual cycle. Power line collisions cause severe injuries — broken wings, lacerations, and death — in birds that cannot detect thin cables at flight speed. Hunting pressure on wintering grounds forces birds into less suitable habitats with inferior food resources, increasing nutritional stress. Disturbance at staging areas during migration forces energy-expensive take-offs and relocations, depleting reserves needed for the next leg of migration. Lead poisoning from ingesting spent shot in agricultural fields causes neurological impairment and slow death. Habitat loss at key staging and wintering sites forces birds into smaller, more crowded areas where competition for food and disturbance from human activity increase chronic stress.
