Summary
[edit]| Description |
English: In most birds, flight generates a specific air movement, or turbulence, around the wings, which we hear as wing whistle. The anterior wing feathers of owls have a comb-like leading edge, which prevents the generation of wing whistle. Supposedly, the comb-like edge generates many micro-turbulences, whose effect combines to muffle the sound of wings moving through the air. Wing whistle is muffled also by the particularly soft and fringed back edge of wing feathers, as well as the soft and soft-edged feathers covering the rest of the body. All of this combines to allow an owl to approach its prey silently and take it by surprise.
