Web1 de mai. de 2002 · Birds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-performance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a … WebBirds’ tails are extremely common ornaments and have provided some of the classic examples of sexual selection probably because they are readily amenable to experi …
