The Australian logrunner (Orthonyx temminckii) is a species of bird that is endemic to eastern Australia where it uses unique foraging techniques and adaptations to search for its food on the floors of temperate, subtropical, or tropical moist lowland forests in south-eastern Australia. Until 2002, it was widely considered to be conspecific with the New Guinea logrunner, but studies showed the two differ significantly, both genetically and vocally.
It is known by a number of common names including spine-tailed logrunner, spine-tail, logrunner, scrub quail and chowcilla.
The logrunner's head and back are a reddish-brown colour; the wings are mainly black; and the tail is dark brown. The wing-coverts are tipped with grey and the eyebrow and ear-coverts grey. The throat, breast and abdomen feathers are white. In the female, the throat is an orange-rufous colour. The male is also larger than the female.
