Migratory birds face welfare threats across their entire flyway from breeding to wintering grounds, requiring international cooperation to protect the habitats they depend on.
Migratory birds experience exhausting journeys of thousands of miles requiring specific stopover habitats for refueling. Welfare threats along flyways include exhaustion from habitat loss forcing longer non-stop flights, illegal hunting and trapping causing injury and death, and light pollution disorienting night migrants. Climate-driven mismatches between migration timing and food availability are emerging welfare concerns. International agreements like the African-Eurasian Waterbird Agreement (AEWA) and the Ramsar Convention on wetlands provide frameworks for protection, but enforcement and implementation varies enormously between countries.
