Hi Don, 
The sulphur-crested cockatoos on Magnetic Island, near Townsville, have the 
usual bunch of screeches etc, but they also have a descending, five note call 
that I've not heard anywhere else, including on the nearby mainland. It's so 
obvious and common, that even some non-birdo mates have asked about it, 
wondering what it was and why they're different. 

Similarly, year-round the resident currawongs have a duet style that is rare or 
absent elsewhere.
