A preen gland is an organ in a bird near the tail, producing oil to help waterproof the bird's feathers. It is also called the Uropygial gland.
The secretion of the preputial gland help with nourishing the prepuce and they also have anti bacterial and anti viral properties which help defend and protect the prepuce.
Without the oily secretion from the preen gland, a water-bird would be unable to stay afloat on water. This would either mean the bird would drown (through being water-logged) or die from starvation through being unable to dive for food.
Most birds will preen several times a day to keep themselves healthy.The uropygial gland, or preen gland, is an essential part of preening. This gland is found near the base of the tail and produces an oily substance that contains diester waxes that help waterproof feathers and keep them flexible. While preening, birds will spread this oil to each feather
