Wikipedia

  1. Uropygial gland

    The uropygial gland, informally known as the preen gland or the oil gland, is a bilobed sebaceous gland possessed by the majority of birds used to distribute the gland's oil through the plumage by means of preening. It is located dorsally at the base of the tail (between the fourth caudal vertebra and the pygostyle) and is greatly variable in both shape and size. In some species, the opening of the gland has a small tuft of feathers to provide a wick for the preen oil (see below). It is a holocrine gland enclosed in a connective tissue capsule made up of glandular acini that deposit their oil secretion into a common collector tube ending in a variable number of pores (openings), most typically two. Each lobe has a central cavity that collects the secretion from tubules arranged radially around the cavity. The gland secretion is conveyed to the surface via ducts that, in most species, open at the top of a papilla (nipple-like structure).

  1. uropygial gland

    The uropygial gland, also known as the preen gland or oil gland, is a large sebaceous gland found in many, but not all, species of birds. Located near the base of the tail, it secretes an oil that the bird uses for preening. This oil helps to waterproof the bird's feathers, maintains their flexibility, and also may play a role in preserving their overall health by having antibacterial properties.
