Migratory birds are key players in our ecosystems.
They act as agents of pest control, and a source of food for other wildlife and, in turn, they protect crops and pollinate plants.
Greylag Goose (Anser anser).
The Greylag Goose breeds in high mountain meadows across northern Western Europe and Siberia, migrating south to the Mediterranean, southern China, and eastern Asia during winter. It often uses agricultural fields like corn, sugarcane, or cereal crops, where it forms large, noisy flocks that can cause significant economic losses. Primarily vegetarian, it prefers wet grasslands rich in small tubers, seeds from floating pods, and soft plant parts . However, its stopover, breeding, and wintering sites are increasingly threatened by habitat loss , dredging of water bodies, and land conversion for monoculture farming or recreational use.
