becausebirds:Scientists had a pigeon, hawk, and owl fly over super-sensitive microphones to measure how much sound was created by their flapping. Owls are known for their silent flying abilities and this is demonstrated by the barn owl in the GIF above. Watch the videoOwls’ near-silence in flight is due—at least in part—to serrated feathers on the leading edge of their wings. These “break up” the turbulence produced by their flight, resulting in less noise being made. -- source link
