Eurasian wigeon populations wintering in the UK have shown significant changes in recent decades. Understanding what drives these trends is essential for effective conservation planning.
Population declines in migratory species like wigeon represent cumulative welfare impacts across the entire flyway. Birds face energetic challenges from longer migrations to find suitable habitat, increased competition at remaining good sites, and exposure to novel conditions at shifting wintering grounds. Maintaining high-quality wintering habitat in the UK is a welfare priority for the thousands of birds that arrive each autumn.
