The mallee emu-wren is restricted to open mallee woodland with spinifex understory in north-western Victoria and south-eastern South Australia. This region is rich in Triodia or as it is commonly known spinifex. The spinifex grass often grows to 1 metre (3 feet 3 inches) in height and provides the optimal habitat for the mallee emu-wren. [9]
The site has been identified by BirdLife International as an Important Bird Area (IBA) because it supports populations of globally threatened malleefowl, black-eared miners and mallee emu-wren, as well as red-lored whistlers, regent parrots and purple-gaped honeyeaters.
The common name of the genus is derived from the resemblance of their tails to the feathers of an emu. [2] The genus was defined by French naturalist René Lesson in 1831 after his visit to Port Jackson on the 1823-5 voyage of the Coquille, although the southern emu-wren had already been encountered and described soon after European settlement at Sydney Cove.

The Murray-Sunset National Park is the second largest national park in Victoria, Australia, located in the Mallee district in the northwestern corner of the state, bordering South Australia. The 633,000-hectare (1,560,000-acre) national park is situated approximately 440 kilometres (270 mi) northwest of Melbourne and was proclaimed in 1991. [2]
Over 200 bird species have been recorded in the park, which is overlapped by the Murray-Sunset, Hattah and Annuello Important Bird Area (IBA), so identified by BirdLife International because it contains mallee habitat supporting a suite of threatened mallee bird, including the malleefowl, black-eared miner and mallee emu-wren.

The endangered Mallee Emu-wren (Stipiturus mallee), endemic to the Murray-Mallee, relies entirely on the species for hunting, nesting, mating, foraging and breeding and rarely disperses out of the hummocks. [17] Additionally, very high lizard diversity and abundance is associated with T. scariosa. [12] [20]
Two large emus on the loose in South Carolina ruffled the feathers of locals a week after dozens of monkeys escaped from a research facility in the Palmetto State.
The striated grasswren is one of 13 species in the genus Amytornis, commonly known as the grasswrens, [2] found only in arid and semi-arid areas of Australia. All are small cryptic birds with long, usually cocked-tails, characterised by diagnostic distinctive interscapular gap in the feathering, [3] an enlarged auditory bulla (tympanic chambers) and ten rectrices.
