I've also tried recording the exact same "species" on my phone, and found the
recording inaudible. Perhaps phone microphones are even less directional than
camera microphones, or perhaps the built in noise cancellation causes it.

oops, forgot to hit reply all, sorry.
Peter, I think you're right about becoming more in tune with the sounds around
you - like the children learning to listen for specific speech sounds in the
audioverbal therapy. It's a question of attention - in other words damage to
the hearing mechanism can affect people's ability to hear differently. But
protection is always good to think about. It is amazing how much noise there is
in our environment now. Just a busy street in the city - you'd be surprised at
the sound levels we're subjected to daily in urban areas and even just in our
own homes.
Couldn't put my hands on my digital recorder last night so I used the recording
device on my digital camera to record what I thought was the screaming call of
a Barking Owl. No such luck - I'm informed it was a vixen. Maybe I shouldn't
have recorded it so I'd always be left guessing... I have also used my phone
but with less success.
cheers,
Arwen
