Bean Goose

      Anser fabalis

      Information

      The fascinating V-formation flights high in the sky of migrating Bean Geese herald the arrival of winter or spring. The birds migrate to their wintering places or breeding areas without taking note of frontiers. This species normally spends the winter to the north or east of Switzerland, in cold winters however, flocks may arrive in the lowland areas of our country.
