74-84 cm, grey, in flight, the light-coloured wing coverts are obvious. This is the progenitor of the domestic goose. Present throughout the year, it feeds in agricultural areas also. It nests in wetlands and valli di pesca (fishing reserves); the pairs are stable and both parents take care of the offspring. In the 1980s, it was reintroduced into the valle Cavanata, Isola della Cona e valle Canalnovo.
