The red-backed thrush or rusty-backed thrush (Geokichla erythronota) is a species of bird in the family Turdidae. Traditionally, it included the red-and-black thrush (Z. mendeni) as a subspecies. It is endemic to forests on Sulawesi and the nearby islands of Buton and Kabaena in Indonesia. It is becoming rare due to habitat destruction.
Geokichla erythronota is very similar in morphology to the chestnut-backed thrush (Geokichla dohertyi) and some authorities believe they are conspecific. Others believe they are distinct. A subspecies (G. e. kabaena) has been named from Kabaena and some researchers believe there is an unnamed race of G. erythronota on the island of Buton, the status of which needs to be evaluated.
The red-backed thrush is about 20 cm (8 in) long and the sexes are largely similar in appearance. Wikipedia →

Possible
About 30% of wildlife watchers report a Rusty-backed Thrush sighting in Tangkoko Nature Reserve on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
August and September
In those months about 50% of wildlife watchers report a Rusty-backed Thrush in Tangkoko Nature Reserve on a given day, against under 5% in April, June and December–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rusty-backed Thrush sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Rusty-backed Thrush sightings: about 30% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Rusty-backed Thrush that you can see in Tangkoko Nature Reserve (order Passeriformes, Perching Birds) are Hair-crested Drongo (about 70%), Finch-billed Myna (about 50%) and Grey-sided Flowerpecker (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rusty-backed Thrush is recorded against all the birds logged in Tangkoko Nature Reserve (30 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.
