When preening, a bird (such as this red lory) draws individual feathers through its beak, realigning and re-interlocking the barbules.. Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.

Once the feathers are fully developed, there are six different types of feathers: contour , flight , down , filoplumes, semiplumes, and bristle feathers.
The gland is invariably present during embryonic development, whereas it can be vestigial in adults of certain orders, families, genera and species. Some or all species in at least nine families of birds lack a uropygial gland, mostly the ones unable to fly or the ones that produce powder down for feather maintenance. [2]
Cul de canard (CDC) (French for "duck bottom") are the feathers from the back of a duck directly around the preen gland (uropygial gland); they are very buoyant due to preen oil produced by the preen gland. They are used when tying dry flies for fly fishing.
Feathers of large birds (most often geese) have been and are used to make quill pens. Historically, the hunting of birds for decorative and ornamental feathers has endangered some species and helped to contribute to the extinction of others. [9]

Ducks generally only have one partner at a time, although the partnership usually only lasts one year. [26] Larger species and the more sedentary species (like fast-river specialists) tend to have pair-bonds that last numerous years. [27] Most duck species breed once a year, choosing to do so in favourable conditions (spring/summer or wet seasons).
