A new study from Cornell University claims to identify a new bird specie (Club-winged Manakins) that creates singing sounds with the feathers of their wings. The study set out to prove that the bird is using its wing feathers to create its violin like sound. The study shows that Manakins vibrates its wings at more than 100 cycles per seconds twice the speed of hummingbirds. Using laysers to monitor feather vibrations, it was observed that the manakins clubed shaped feathers vibrate at 1500 hertz. This is the same frequency of the sound made by the manakins. There are also other birds that use their wings in this manner. This new evidence places this bird with arthropods which also uses their wings to produce singing sound such as crickets
