The southern scrub robin (Drymodes brunneopygia) is a species of bird in the family Petroicidae, the Australasian robins. It is endemic to Australia, where it occurs in mallee and heathland in the semi-arid southern parts of the continent. Its range includes several disjoint regions from central New South Wales through western Victoria and southern South Australia, through to the southwestern area of Western Australia. It is a relatively dull and large robin, with adults around 19 to 20 centimetres (7.5 to 7.9 in) in length, of which around a third are the tail feathers. Most of the plumage is grey. It breeds between July and December and has a nest on the ground, built of twigs and lined with twigs, grass and bark. Unusually for a passerine, it lays only a single egg. This southern scrub robin was photographed in the Nombinnie Nature Reserve in New South Wales.
