We have detailed notes in the pdf on all the subspecies we saw (Kai, the
link to the reprot is in my previous email) - I only wrote up the species I
know are or have been very close to being split, and agree there are many
others. We saw a few of the ones Kevin mentioned (eg: Thrush on Mount
Lewis, Brown Gerygone everywhere, the dark Grey Fantail, etc), but for the
moment there isn't much movement on any of them taxonomically speaking I
don't think. The Cape York finches were unfortunately not gettable on our
trip since we didn't go on the PDR or to the west Cape, though they
certainly warrant looking at - very different birds by the looks of it.

I hadn't heard of the Wet Tropics Cicadabird Mike - do you know what the
field differences are? We had good views of a couple of birds around
Julatten and Davies Creek Road.

Cheers,
Josh
