    ..Many kinds of birds are reported to create aerodynamic sounds with their wings or tail, and this model may explain a wide diversity of non-vocal sounds produced by birds...

    ..Third, laboratory experiments indicated that both P8 and P9 can produce tones over a range of 700-900 Hz. The wings therefore produce the distinctive flight sound, enabled via subtle morphological changes to the structure of P8 and P9...

    Christopher James Clark
    Department of Integrative Biology, University of California, Berkeley, Berkeley, CA 94720, USA
    Proc Biol Sci 276:2109-15. 2009
    ..The effects of elongation are thus subtle and airspeed-specific, suggesting that diversity in avian tail morphology is associated with only modest flight costs...

    Proc Biol Sci 276:3047-52. 2009
    ..Stereotyped courtship behaviours offer several advantages for the study of extreme locomotor performance, and can be assessed in a natural context...
