Tawny Owl Feather, SEM by Power and Syred/Science Photo Library: The comblike structure of the leading edge of an owls wing with filamentous extension of their anterior barbules on their feathers breaks turbulence into micro turbulence, muffling sound and giving owls the benefit of silent flight. Most other birds and including raptors (and some daylight hunting owls) do not have this structure. http://tinyurl.com/3mtgr59  #Owl_Feathers #Tawny_Owl #Feather #SEM #Power_and_Syred_Science_Photo_Library
