Where are Filoplume feathers?
Filoplumes are hairlike feathers with a few soft barbs near the tip. They are associated with contour feathers and may be sensory or decorative in function. Bristlelike, vaneless feathers occur around the mouth, eyes, and nostrils of birds.
What is the purpose of Filoplume?
Filoplumes are associated with sensory receptors in the skin, and are thought to provide information about wind, air pressure, and feather movements that birds use to maintain efficient flight. Bristles are short and stiff and lack barbs along most of the rachis but the base.

Semiplume feathers are found underneath contour feathers and are used for insulation Filoplume feathers are incredibly small. They have a tuft of barbs at the end of the shaft. Unlike other feathers which are attached to muscle for movement, filoplume feathers are attached to nerve endings.
Are filoplumes degenerate contour feathers?
Some ornithologists disagree with the theory that filoplumes are degenerate contour feathers and believe instead that they are sensitive structures that assist in the nerve endings in the follicle. It is therefore quite possible the filoplumes play a key role in keeping contours in place during preening, display, and flight.
