... http://www.biologists.com/user-licence-1-1/ Summary: The sexually selected 9 kHz wing trill of male Allen's hummingbirds is substantially louder in maneuvers than in rectilinear flight, and appears to be produced in supination. Adventitious sound Locomotion-induced sound Sonation...

...Robert L. Niese; Bret W. Tobalske ABSTRACT For centuries, naturalists have suggested that the tonal elements of pigeon wing sounds may be sonations (non-vocal acoustic signals) of alarm. However, spurious tonal sounds may be produced passively as a result of aeroelastic flutter in the flight...

... of non-vocal sonations. The most prominent sonations are single or multiple intense ‘wingsnaps’ with a dominant acoustic frequency around 5 kHz. Several hypotheses have been proposed addressing the source of the sound, ranging from purely aerodynamic origins (due to a rapid jet of air formed by the wings...
