Migratory birds face welfare threats that span multiple countries and continents, requiring international cooperation to address the cumulative impacts of habitat loss, hunting, and climate change along flyways.
Migratory bird welfare is one of the most complex welfare problems because it requires coordinated action across the full geographic range of species that may span six continents. A bird protected in its breeding range is still vulnerable to illegal hunting at its wintering grounds or wetland loss at critical staging sites. Effective welfare improvement requires the international frameworks that match the international reality of migratory species' lives.
