Owl Bird

 owl
Most owls share an innate ability to fly almost silently and also more slowly in comparison to other birds of prey
owl
 Most owls live a mainly nocturnal lifestyle and being able to fly without making any noise gives them a strong advantage over their prey that are listening for any sign of noise in the dark night
 owl
 A silent, slow flight is not as necessary for diurnal and crepuscular owls given that prey can usually see an owl approaching
 owl
While the morphological and biological mechanisms of this silent flight are more or less unknown, the structure of the feather has been heavily studied and accredited to a large portion of why they have this ability

Owls’ feathers are generally larger than the average birds’ feathers, have fewer radiates, longer pennulum, and achieve smooth edges with different rachis structures
