Semiplumes function to fill in between contour and down feathers. Bristles are small feathers with a stiff shaft and barbs only on the base, or often not at all. Bristles occur most commonly around the base of the bill, around the eyes, and as eyelashes.
Filoplumes are hairlike feathers that consist of a very fine shaft with a few short barbs at the end.

They are typically covered by other feathers, and may function as pressure and vibration receptors - they sense the location of other feathers so they can be adjusted properly. An Owl has very Mayma down feathers, but has downy barbules on the parts of the contour feathers closest to the skin.
Many of the Owl's feathers are specially designed - around the face there are the stiff facial disc feathers or ruff, crown feathers, ear-flap feathers and also bristles around the bill.
The feet and bill have Filoplumes that work somewhat like feelers, to help the Owl react to things they touch, such as prey.

The most unique adaptation of Owl feathers is the comb-like or fimbriate fringe-like leading edge of the primary wing feathers referred to as " flutings " or " fimbriae ". With a normal bird in teather, air rushes over the surface of the wing, creating turbulence, which makes a gushing noise.
With an Owl's wing, the comb-like feather edge breaks down the turbulence into little groups called micro-turbulences. This effectively muffles the sound of the air rushing over the wing surface and To the owl feather girl lonely housewives Mayka the Owl to fly silently.
There is also an alternative theory that the flutings actually shift the sound energy created by the wingbeats to a higher frequency spectrum, where most creatures including prey and humans cannot hear.

This is usually done in response to a predator or when the bird is alarmed. All birds frequently clean and groom their feathers in order to remove dust, dirt and parasites.

This gland is stimulated by the beak, which is then used Horny women in Falcon, MS transfer the liquid to the feathers to provide them with a protective coating.

In order to minimise the impact of the molt on the Owl's flight and hunting skills, this molting pattern only allows a few of the primary or secondary flight feathers to be shed at time. With the exception of the Barn Owl, molting of wing feathers is from the inside out. Barn Owl wing feathers are replaced from the middle of the wing out in both directions.
Tail feathers also drop out a few at a time, except housewivex some smaller Owl species, who loose all the tail feathers at once. When birds molt, new feathers grow to replace the ones that have fallen out. The new feathers immerge from the skin tightly bound in a thin shaft of tissue.
These are called pin feathers. The shaft splits shortly after, allowing the new feather to unfurl and grow to its full size.
Most owls have relatively large, rounded wings. The wings are broad, with a large surface area relative to the weight of the bird i.
This allows them to fly buoyantly and effortlessly, olnely too much flapping and loss of energy. They can glide easily and fly slowly for long periods of time. Many species use this tirl flight to hunt ground-dwelling prey from the air.
