It is a small, brownish bird with a distinctive yellow rump and thin dark bill. It inhabits savannah, scrub and forests across most of Australia and eats insects. The species engages in cooperative breeding.

This small thornbill is widespread across much of Australia and is easily recognized by its bright yellow rump. It commonly forages in small, busy flocks on or near the ground and often benefits from human-altered habitats like parks and farms. The species practices cooperative breeding, with helpers assisting a breeding pair. Its quick, tinkling calls help flocks stay in contact while moving through low cover.
