This practice may be approached through preventive and/or interventive techniques.
Pennaceous feathers are relatively stiff and flat; the flight and contour feathers are of this kind. They have stiff barbs branching from the main trunk of the feather (the rachis). These barbs in turn have barbules branching off of them, the barbules have hooklets spaced evenly along their length and hook together to form a stable smooth surface.

"Feather dust" left on a window after a birdstrike. Powder down, or pulviplumes, is a special type of down that occurs in a few groups of apparently unrelated birds. In some species, the tips of the barbules on powder down feathers disintegrate, forming fine particles of keratin, which
