POST - Mystery Bird Call - Royal National Park, NSW

[Marc Anderson <>]

Hi all,

Whilst recording the dawn chorus on the banks of the Hacking River, 
Royal National Park, NSW, I heard a call which I've never noticed 
before. It was coming from high up in a tall eucalypt and sound somewhat 
like a referee’s whistle. The closest call I could think of is that of a 
Fan-tailed Cuckoo (not the descending trill, but the peeuw-weeeuew call 
as recorded here) . But this mystery call was consistently slower than 
the FTC and repeated dozens of times in more or less the same way. If 
anyone has an ID or suggestion I would be interested to know what you think.
One birder has suggested it may be Brush Cuckoo - what do you think?
