A duck can swim in water because its feathers are not afraid of water. The duck's tail has a caudal fat gland, which continuously secretes fat. Ducks often turn their heads, put their heads on their tails, and then wipe their feathers around by applying the fat to their feathers.

The fat separates the water from the feathers, so the duck's feathers do not get soaked in water.
