The ducks are bred for their meat, eggs and feathers. The wild ducks are also subject to sport hunting. Inhabit the wetlands of the Catalan Countries. Adult males spend periods without flying to protect their habitat if they have sufficient food reserves. Shed feathers of the wings of all time, which forces them to stay hidden for a time, as their ability to escape is diminished at this time.
