Feeding Habits
Slender-billed Thornbill's diet consists mainly of various arthropods, seeds, and vegetables. It forages in pairs or groups, often with other species, by gleaning and occasional sallying throughout the day, avoiding extreme heat. Unique clan-like assemblages are observed over months.
Habitat
Slender-billed Thornbill primarily inhabits chenopod shrublands rich in vegetation like samphire, bluebush, and saltbush, thriving in salt-tolerant ecosystems ranging from coastal to semi-arid and arid inland areas. It is also found in mangrove terrains, acacia shrubland near samphire flats, and sclerophyll heathland with endemic flora such as sheoak and Melaleuca species. This species shows a preference for habitats with post-fire regenerating vegetation and can occasionally occupy areas near shallow freshwater wetlands intermixed with low shrubbery.

Distribution Area

The slender-billed thornbill iredalei subspecies has six separate and isolated populations in Western Australia, and a large population in the Carnarvon bioregion. The hedleyi subspecies ranges across eastern Australia, and the rosinae subspecies can be found in southern Australia.

Species Status

The rosinae subspecies, most commonly found in Gulf St Vincent, is considered vulnerable. The hedleyi subspecies, whose territory includes most of eastern Australia, is considered near threatened. The iredalei subspecies is also considered Vulnerable. The thornbill (iredalei subspecies) is extinct in northern Australia, and is considered the only indigenous species to have become extinct in that location since European settlement.
