continutaion:

using the uropygial gland (preengland or oilgland)


Basically, the uropygial gland produces oils that a bird squeezes from it in order to apply to its feathers, thereby waterproofing them. Uropygial comes from Greek words meaning “rump” and pygostyle from the Greek meaning “rump pillar.” The uropygial gland, also called the preen gland or oil gland, is a bilobed structure on the dorsal base of a bird’s tail between the fourth caudal vertebra and the pygostyle, the structure formed by the fusion of the final caudal vertebrae.

(In birds, the oily secretion of the rump gland primarily:
protects feathers against moisture and ectoparasites
strengthens and makes feathers more elastic.)
