Help with underwater identification please

["peter" quies_still]

Hello group,

I=92ve been doing a lot of hydrophone recordings and I=92d like to know wha=
t I=92m listening to.

This one in particular: https://www.dropbox.com/s/cmhjztrin598ct2/1001%20Ce=
ntennial%20Park%20Pond%20%28Excerpt%29.wav?dl=3D0

These sound like cicadas, but just for your reference, I could only hear th=
is with the hydrophones, so it definitely wasn=92t loud cicadas above water=
 being picked up by the hydrophones under water.

Also for context, this was recorded in one of the ponds in Centennial Park =
in Sydney in June, or the end of autumn, if that helps to identify.

Thanks for your help

Peter
