Powerful Owl call?

[Brian Hawkins <>]

G'day Tom and Birding Aus,

I have heard the Common Green Treefrog, Litoria caerulea, make a very similar 
sound when threatened (for instance by a Black Rat).

Hi All,

Have just finished my part of the QUT sensor work and found an interesting
call at 21.18hrs on 15 October 2010 at the SERF site in Samford, SE Qld. It
was very wet at the time and there are a lot of insect and frog noise in
the background but the call is quite distinct and repeated up to ten times.
I initially thought it might be Masked Owl but Julie Sarna (who is a
colleague of mine on the project) alerted me to the possibility that it
might actually be a Powerful Owl. in the past I have heard this species
make a shrill-chatter in daytime but can't remember if is similar to the
one recorded. See http://www.aviceda.org/audio/?p=208

Any comment very welcome.

Tom
