Alright, I'll bite!
On some recent surveys in the Edenhope-Natimuk-Dergholm
area (broadly speaking: the region west of Horsham to the
South Australian border, and south of the Little Desert),
Southern Emu-wrens were recorded at very few sites in the
Dergholm area and at a spot ESE of Edenhope. This last
location is close to Jilpanger Scrub but is not as far
north. Since the emu-wren sightings are second hand, I'm
not sure of the exact details but occurrences of the other
wrens mentioned were as follows. Superb Fairy-wren was
found at the same sites as the emu-wrens and Variegated
Fairy-wren was recorded at a couple of sites. All three
species were not recorded together at a site.
>From my own wren sightings in the area and the survey
information quoted, I can't work out how the different wren
species co-exist in an area as they appear to like similar
habitats.
Lawrie, did you record the different wren species in
distinct habitats (out of the list that you noted) in
Jilpanger Scrub) and did you record the three species on
the same visit or one/two species over several visits?
Other inland emu-wren occurrences that I know of in western
Victoria are in the Grampians, not far from Jilpanger, and
at a reedy basalt stony-rise swamp west of Colac. Superb
Fairy-wrens occur in these areas but Variegated Fairy-wrens
don't as far as I know.
