After seeing the Port Macquarie bird with Chris, I did some homework on 
the calls of A.orientalis comparing the call of the Port Macquarie bird  
with calls from a bird taped at Fogg Dam and birds taped at Ambon Island  
in the Moluccas, all proved to be identical.   
As a final check each of these tapes were sent off to Hong Kong for  
comparison with their records/calls of A.orientalis and A arundinaceus  
again the results were positive, ruling out any possibilty of  
A.arundinaceus or A stentoreus. So the main criteria for acceptance of  
the Port Macquarie bird as A.orientalis was its call.  Fred Van Gessell  
being the person who found this bird, doing so on call alone. This was  
because of his familiarity with A.orientalis calls from the NT and  
However having said this, there does appear to be considerable variation 
in the calls of A stentoreus (Australian Reed Warbler). The birds around 
Halls Creek and Kununurra sound considerably different from those  
locally here in Sydney. David Stewart I know has both on tape.
