Rare
Under 5% of wildlife watchers report a Slaty-backed Thornbill sighting in Uluru-Kata Tjuta National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 80th most-seen of the 84 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and July
In those months about 10% of wildlife watchers report a Slaty-backed Thornbill in Uluru-Kata Tjuta National Park on a given day, against under 5% in June and August–April, the lowest months. Those are among Uluru-Kata Tjuta National Park's driest months, with about 10 mm of rain a month against 65 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Slaty-backed Thornbill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Uluru-Kata Tjuta National Park, in our data
Uluru-Kata Tjuta National Park is the only park on Wallace's Line with enough records to rate Slaty-backed Thornbill sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Slaty-backed Thornbill is recorded against all the birds logged in Uluru-Kata Tjuta National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
