Slaty-backed Thornbills are very small bushland birds. Their
forehead is striated black-on-grey, while the rest of the front
(from the throat down to the undertail coverts) creamy-white.
The cap and nape of the neck are slate-grey, while the wings are
darker grey and the tail even darker grey, with a thin lighter
terminal band. The rump is cinnamon-coloured. The cheeks are
whitish with grey specks. The irises are reddish-brown; the bill,
legs and feet are dark-grey.

Twitcher's tip |
|
Slaty-backed Thornbills have no striation on the front, which
distinguishes them from the heavily streaked Inland Thornbills.

and range
The overall distribution of this species can be assessed, and
specific locations where birds have been spotted can be found,
based on individual sighting reports submitted by birdwatchers to
ebird.org
.
The global distribution of the Slaty-backed Thornbill is available
HERE
.
NB:
Reports on ebird of birds submitted by birdwatchers from
the Australian Outback tend to be clustered along roads
and public areas such as camp grounds; in such cases their
distribution is not a good representation of the overall
distribution of the species.
Slaty-backed Thornbills are endemic to Australia.
They are found only in the red centre of the Australian continent,
including some of the most arid parts. Their range extends from
central inland WA, off the coast at geographical latitudes between
the tropic of Capricorn and about that of Geraldton, WA, across
the border with the southern NT and northern SA, to the western
side of Lake Eyre. Further North, there is a finger-shaped
extension to their range through the southern NT, into western
QLD to the South of Mt. Isa, into central QLD.
Slaty-backed Thornbills can be found in semi-arid to arid inland plains
with mulga-dominated
scrub.

The identification of this bird is uncertain, mainly because it
was spotted outside its nominal range, in the Gammon Ranges in SA. We
tentatively identify it as a Slaty-backed Thornbill, because its
back is darker grey than those of the similar Inland Thornbill or of the
Chestnut-rumped
Thornbill.
