I was not clear in the message. What thy are arguing about is not the
calls etc of the bird but the sounds of the wingbeats. Part of the
evidence is that obtained by the wingbeats recorded of a real Ivory
Billed. The speed is supposed to be different from that of a PIWO. A
person has done a study in regular flight but the bird in question is
just taking off so just thought if any of you knew were to something up
where you hear the wingbeat of a bird launching into flight might help
things out.
