GEESE
True geese are medium to large birds, always (with the exception of the Nene) associated to a greater or lesser extent with water. Most species in Europe, Asia and North America are strongly migratory as wild birds, breeding in the far north and wintering much further south. However, escapes and introductions have led to resident feral populations of several species. Geese have been domesticated for centuries. In the West, farmyard geese are descended from the Greylag, but in Asia the Swan Goose has been farmed for at least as long.
