Physical description Click here for a physical description Inland Thornbills are very small bushland birds. Their forehead is freckled black-and-white, the sides of the face and the throat and chest are heavily streaked black on white. The belly is light-cinnamon, the flanks pale-buff. The back is grey-brown, with a red-brown rump and a brown tail that has a black end with a thin grey terminal band. The irises are red, the bill, legs and feet are dark-grey. Twitcher's tip Inland Thornbills have a heavily striated front, which distinguishes them from Inland Thornbills with their plain front.

Taxonomy, classification See Inland Thornbill at Wikipedia .

Range, habitat, finding this species Click here for information on habitat 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 Inland 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. Inland Thornbills are endemic to Australia. There are four races of Inland Thornbills - for details see a field guide. They populate the semi-arid interior of the southern half of the Australian continent, i.e. the entire western half of WA up to the tropic of Capricorn, the north-western and south-eastern quarter of SA plus much of the southern half of the NT, as well as most of inland NSW and subtropical QLD. They are not found in the Simpson Desert, the Nullarbor or the eastern half of WA, not along the South or East coast of the continent and not in the tropics either (with only minor exceptions, e.g. near Mt. Isa, QLD). Inland Thornbills can be found in low shrubs, heath and mallee in semi-arid environments.

Sightings Click here for sighting information Race "apicalis" J. Greaves reports spotting an Inland Thornbill, nominate race "apicalis", at Manjimup, WA, in March 2015, in Balingup, WA, in May 2016, and at Wave Rock, near Hyden, WA, in March 2017. M. Eaton reports finding Inland Thornbills, nominate race "apicalis", at Margaret River, WA, in April 2019. Race "apicalis", or a mix between different races, was sighted by us in Flinders Ranges NP, SA, in March 2008. R. Plumtreereports finding an Inland Thornbill, nominate race "apicalis", at Parachilna Gorge, SA, in November 2018. Race "albiventris" Our first sighting of an Inland Thornbill, race "albiventris", was in February 2006, near Gunnedah, NSW. In August 2006 we found Inland Thornbills, race "albiventris", 20 km South-West of Narrabri. We see them semi-regularly at Eulah Creek and also Deriah Aboriginal Area, 20-30 km East of Narrabri. Inland Thornbills, race "albiventris", were spotted by us at Dandry Gorge AA in June 2016. A family clan of Inland Thornbills, race "albiventris", was found by us at the Goulburn River NP, in December 2015. In September 2017 we found Inland Thornbills, race "albiventris", at Gundabooka NP, near Bourke, NSW. Race "whitlocki" Inland Thornbills of race "whitlocki" were spotted by us in the Gammon Ranges, SA, in March 2008.
