The Chestnut-rumped Thornbill (<em>Acanthiza uropygialis</em>) is a small insectivorous passerine in the family Acanthizidae, widely distributed across arid and semi-arid Australia. Detailed plumage and behavioral descriptions of this species are limited in the available literature. It is associated with grassland habitats, often foraging on or near the ground in open areas with sparse vegetation. The species constructs a domed nest (DM type); clutch size typically ranges from 2 to 4 eggs, with incubation lasting approximately 19 days and fledging at 18–20 days. The Chestnut-rumped Thornbill is assessed as Least Concern by the IUCN. Research indicates it is a widespread and common species across Australia's interior grasslands and open scrublands.
