Solution:
Preen gland, also called Uropygial, or Oil, Gland, is the most prominent epidermal gland, located on the back near the base of the tail in birds, and produces a waxy, oily secretion via two or more ducts. This oil is spread through the plumage during preening. The primary function of preening behaviour is to waterproof the feathers by distributing preen oil from the uropygial gland at the base of the tail to the feathers.
Birds do not have glands in their skin but preen gland. The secretion by this gland is used for grooming action in feathers and making them waterproof. Similarly, class Reptilia also have dry skin; on the other hand, Mammals, however, have a number of glands in their skin.
