Secret behind owls’ near noiseless wings

Many owl species have developed specialised plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.

Findings revealed that owls possess three physical attributes that contribute to their silent flight capability. They include a comb of stiff feathers along the leading edge of the wing, a flexible fringe on the trailing edge of the wing and a downy material distributed on the top of the wing.
