We recognize the gray goose by its triangular orange bill, flat head and blue-gray wing-bowl. From the moment it lets out its call, no experience is possible. It is the largest of the brown geese, all of which have more or less brown feathers with white undertones.
The gray goose is the only species that breeds in Western Europe. Originally it lived here and it was ancestor and mother of all European domestic goose breeds. Thanks to its beak, that goose has a very wide food pattern. Therefore, she was also domesticated unconsciously. Its call is that of the barnyard goose of the light type.
They become so numerous that they can cause enormous damage !
