I thought this discussion had been resolved last time this split was discussed
about 3 months ago!
However, to add to the confusion, if you look at Schodde & Mason (1999) which
is the best distribution reference for subspecies of passerines in Australia,
the siyuation is complex.
clarum and fordianum interbreed on an extensive front in both SW WA and western
SA. However, in central SA all three 'former' subpecies interbreed
(particularly on the Eyre Peninulsa) and only 'pure' castanotus occutrs east of
Spencer Gulf (Port Augusta) - immediately west of here is castanotus/clarum
hybirds.
This is I assume based on assessment of a number of specimens, and also on the
paper Ford (1981) which was published in Emu.
I am certain I will get comments on my terminology here (and I haven't read the
recent paper proposing the split) but the Quail-thrush are quite variable (with
some suggestions on plumage reflecting soil colours) and so to be confident of
which species you can tick would need to be well into the range of each
subspecies (I haven't seen fordianum, and have only heard clarum near Uluru, so
this is one split that hasn't made my list yet).
Cheers,
Peter
