The Australian Logrunner (Orthonyx temminckii) is a distinctive medium-sized passerine, celebrated for its unique foraging behavior. Males are striking with a black head and upperparts, a brilliant white throat, and a rusty-orange breast, accented by a prominent white supercilium, while females are similarly marked but sport a rich chestnut throat and breast, making sexual dimorphism quite pronounced. Measuring approximately 18-20 cm in length and weighing 50-70 grams, its most notable physic...
Dense, moist temperate and subtropical rainforests, wet sclerophyll forests, and adjacent gully thickets, primarily at lower to mid-elevations below 1200 meters.
Primarily insectivorous, feeding on a wide variety of invertebrates such as insects, larvae, worms, and snails, obtained by disturbing leaf litter and rotten wood on the forest floor.
The Australian Logrunner is a highly terrestrial and diurnal species, spending most of its time on the forest floor. Its foraging technique is extraordinary: using its powerful legs and stiff tail as a prop, it performs a characteristic 'log-rolling' action, kicking aside leaf litter, small logs,...
The Australian Logrunner is endemic to the coastal and escarpment rainforests of eastern Australia, spanning from southeastern Queensland southwards into eastern New South Wales.
