Duck feather are insulators and they are also water proof so that they shed water. Ducks have a special gland near their tails, called the preen gland. This gland produces an oil, which ducks rub over their feathers with their beaks to maintain their waterproof effect. The larger feathers in the tail are called quill feathers and were used at one time for writing.
