Hi all,

A note from Chris Benesh offering thanks and comments.

More than likely relieved it is possibly not a PA system;-)

Very best and thanks again to all.

Hey Alan,

Thanks for taking this on and for forwarding your comments.  

Intriguing ones from Lloyd.  

If you could forward my brief comments to the list in response to his that 
would be great.  

When I was first hearing the call, I actually wondered if it could be a 
Magpie-lark doing the entire suite of sounds.  But I noticed a couple of 
instances when the vocalizing birds seemed to be "talking over" one another.  
In the recorded example, there is some "talking over" that occurs in the 
penultimate series, at about the 33.6-35 second mark, where two whistles of the 
mystery bird are "stamped on" by the Magpie-lark.  This blending of notes does 
not occur elsewhere in the cut and is suggestive of two birds being responsible 
for the sounds being heard (in my mind).  

Of course, that doesn't rule out a bowerbird as being one of the two involved.  

I am grateful to all who have provided their thoughts so far. I feel a little 
better knowing that it wasn't something "easy".
