Yes, I did mean the BOCA CD. I tried playback on a number of occasions, 
including once when a whistler was in earshot, to no avail. When I stalked the 
red-lored whistler by following its calls, the I-pod was back in my vehicle.  

As a matter of interest, earlier that day I encountered a pair of whistlers 
calling to each other with red-lored calls, but when I managed to see one of 
them, it was a female Gilbert's.  I was not using playback at this time. 
Another birder later told me that on one occasion when he played red-lored 
whistler, a Gilbert's came in.

In retrospect, I wonder if using playback when very close to the red-lored 
whistler would have made a difference. I guess that my experience does not 
throw much light on whether regional differences matter, but I do think that 
Gilbert's can imitate red-loreds, or share very similar calls.

Carl, the birdAus CD? Do you mean the BOCA CD?

Did you use any playback? We found one in Murray Sunset NP in Victoria, and 
decided to try to get it closer for a photo. It ignored the first 20 seconds(?) 
or so of the track, then responded strongly to a particular call after that.

I'm wondering if regional variations on the track matter to the birds.
