Biology
It prefers lakes, estuaries, lagoons and bays during the winter season; during the reproductive period, it prefers swamps, meadows and rivers. In Italy it is double-handed (August-November February-March), occasionally breeding. Fly in tight flocks (V), walk with ease and rise directly from the surface of the water. Usually he reaches the shore at dusk to eat. Its diet is mainly vegetable, but also molluscs, insects. The species is monogamous, the female lays only once a year, 7-8 cream-colored eggs without speckling, which hatches for 25 days and after the female takes care of the offspring for 6 weeks.
The population seems to have suffered from reclamation and hunting.
It does not willingly join other ducks, and the female often takes on the colors of the male.
