Flag has ladies all of a flutter
Date:4/28/2010

ast ideal hinged plates would do so, and found excellent agreement between prediction and experiment.

Dr Ennos said: "The snipe has a special outer tail feather that he can stick out. The feathers have a weakened hinge region in their rear vane so they flutter like flags to produce the noise, which the males use to attract females. They dive to increase their speed and make a more attractive higher-pitched sound.

"We got the idea of studying this mating call from work on more exotic hummingbirds, but we have shown that our own home-bred snipe are just as ingenious. Our first tests were carried out on specimens from Manchester Museum, but we obtained most of our feather through ebay!"

His colleague Dr Jonathan Codd added: "These are significant findings because unlike other birds that produce sounds (such as Annas hummingbird) the entire length of the rear part of the feather vane is mobile, acting as a single unit."
