Many thanks to David and Denise for enlightenment. I had already gleaned from hanzab that there had been the odd earlier NT record, but found it odd that birders don't seem to report them nowadays. Clearly they ARE there, and I wasn't reading the right literature. And David, back in 1996 when hanzab V3 was published, there was doubt even then about it being affinis, or the nominate nilotica. It seems that in recent times the term affinis has become more widely accepted. Can't recall on what basis, but I guess in the coming years we will learn more. This is really tricky stuff. From memory, I think Danny Rogers' paper favoured affinis.

The point is that they certainly aren't macrotarsa, and thanks for taking the time to communicate.

Hi David and Jill
In Annotated Birds of the Top End (Thompson and Goodfellow, 1990), several
sightings of S.n. addenda (as we knew it) are reported from Leanyer Sewage
Ponds, Fogg Dam and Kakadu by John McKean and others.  These birds visit
Darwin during the Wet Season.

A specimen from the sewage ponds was found in December 1989, and I assume
this in the the NT Museum collection, if anyone is interested.
