Question:
Why do doves wings whistle in flight?

Replies:
The vibration at the tip of the flight feathers in the rear of the wings create the whistle vibrations. The contour of the flight feathers aid in the type of vibrations (sound) as well as the interlocking barbs. Most birds produce some sort of vibrations, but may be inaudible to humans. Owls on the other hand, have special feathers at the end of their wings that prevent the virbations that cause sound. Their quiet flight is essential to their successful in capturing food for the sound would alert the potential prey.
