| Résumé : | The 'wing-clapping' noise given by displaying male European Nightjars Caprimulgus europaeus is generally considered to be generated by the primary tips being struck together in flight. However, observations and audio recordings suggest this might not be the case. Rather, there is evidence in favour of the sound being generated by a 'whiplash-like' mechanism. Here, we review the evidence supporting this theory, both from the literature and from our own observations and recordings. |
