Billions of migratory birds traverse global flyways each year, facing welfare threats from illegal killing along migration routes, habitat loss at stopover sites, and the physical demands of crossing deserts, seas, and mountains.
Migratory bird welfare challenges compound across the full annual cycle. Breeding ground habitat loss reduces reproductive success. Stopover site loss forces birds to attempt crossings without adequate fuel reserves, causing exhaustion and mortality. Illegal killing in Mediterranean countries removes millions of birds from populations already stressed by habitat loss. Light pollution causes disorientation and building strikes that kill billions annually. Climatic changes at breeding, wintering, and stopover sites create phenological mismatches that reduce food availability during critical periods.
