It is characterized by prominent serration of the glands and the presence of generalized low-grade dysplasia.

Researchers from Japan and China studied the serrations in the leading edge of owls’ wings, gaining new insight into how they work to make the birds’ flight silent.

Owls are known for silent flight, owing to their unique wing features, which are normally characterized by leading-edge serrations, trailing-edge fringes and velvet-like surfaces.

These owl-inspired leading edge serrations, if applied to wind turbine blades, aircraft wings or drone rotors, could provide a useful biomimetic design for flow control and noise reduction.

The researchers analyzed owl-inspired feather wing models with and without leading edge serrations, by combining large-eddy simulations – a mathematical model for turbulence used in computational fluid dynamics to simulate air flows – and Particle-Image Velocimetry (PIV) and force measurements in a low-speed wind tunnel.
