The graylag goose (Anser anser) is a large waterfowl species native to Eurasia and North Africa, recognized as the principal ancestor of most domestic geese breeds. Described by Carl Linnaeus in 1758, these birds inhabit wetlands, marshes, and lakes, where they graze on grasses and aquatic vegetation. Adults display a bulky gray-brown body, a pale edge to their upper wings, and a distinctive orange or pink bill. They are highly social outside the breeding season, gathering in large migratory flocks.
