I'm very confused by all this. I've been to all the locations mentioned and
seen Grasswrens, but now don't know which sp and ssp I've seen where. I just
wish someone would publish a definitive listing of which birds are in which
locations -- can do, please?

Subject: New Grasswren Species
G'day all, It would be very interesting to get the current taxonomic musings
for our grasswrens, especially the Striated GW complex. Firstly, I must
apologise in advance for my simplistic understanding of taxonomy, but I do
hope that my questions & thoughts below are seen as very much that of a
layman... Richard B has commented that whitei & rowleyi may be next to be
split from Striated. I've often wondered how much habitat preference would
play in this. Apart from morphological differences, the Short-tailed
merrotsyi is a rock inhabiting species, quite unlike the nominate race
striatus of Striated, which is a sandplain bird. Race rowleyi of Striated is
also a sandplain inhabitant, well, at least from my observations. Yet, race
whitei inhabits rocky terrain. There must be a lot more to it than just
sandplain vs rocky terrain, but I wonder why it has been mooted that rowleyi
is the next most likely race of Striated to be split, given that it a
sandplain bird (at least from
my experience). I would have thought that whitei being a bird of rocky
terrain (as is merrotsyi Short-tailed GW), would be one to consider very
closely. It would be interesting to get others' thoughts on this..... Cheers

> Yes, Jeff and Martin you're absolutely correct. I did have my ssp mixed
up. The new Thick-billed is the one many people see at the whiteface site
at Lyndhurst and surrounds. My visit to Mt Ive was two fold as I'd only
ever had very poor, barely tickable views of Short-tailed in the Flinders
and wanted to see them again.

that the Whyallah birds are found on the hill tops in the Conservation Park
near town. I've never been there but this is something I've often wondered
about. Perhaps someone who has been to Whyallah CP can comment on this.
