What are owl feathers like?
An owl’s primary feathers are serrated like a comb. This design breaks down turbulence into smaller currents called micro-turbulences. Then the edge of the feather muffles the sound of air flowing over the wing and shifts the angle at which air flows.
Are owl feathers soft?
Those smaller streams of air are further dampened by a velvety texture unique to owl feathers and by a soft fringe on a wing’s trailing edge. These structures together streamline the air flow and absorb the sound produced. The sound-dampening structures didn’t evolve by chance. On the right, the trailing-edge fringe.
What texture does a feather have?
Down feathers are fluffy because they lack barbicels, so the barbules float free of each other, allowing the down to trap air and provide excellent thermal insulation. At the base of the feather, the rachis expands to form the hollow tubular calamus (or quill) which inserts into a follicle in the skin.

Why do baby owls have soft feathers?
Feathers. The owls’ feathers are very soft – another adaptation for quiet flight; The flight feathers are covered in a thin hair-like structure that traps air within the feather surface. This helps to maintain a smooth air-flow across the wings and thereby avoid stalling at very low airspeeds.
What are fluffy feathers called?
Down feathers are small, soft, fluffy, and are found under the contour feathers. There are special types of downy feathers called powder down feathers. When the sheaths or barbs of these feathers disintegrate, they form a fine keratin powder, which the bird can spread over its feathers as a water-proofing agent.
Why do owls have such thick feathers?
