Description

The Striated Grasswren is similar in appearance to the related fairy-wrens (Malurus spp.), though significantly larger in size (14.5 - 18.5 centimetres). The upperparts are a soft reddish-brown, with white streaks while the underparts are buff with heavy white streaking on the breast. The eyebrow is rufous-brown and a heavy black whisker-streak is present. The throat is white, the bill blackish and legs bluish-grey. The tail is long and held cocked and is blackish-brown in colour. The sexes differ slightly in plumage with the female having pale chestnut flanks. Immatures are slightly duller.

Distribution

This species is widely distributed through the arid and semi-arid regions of mainland Australia, with three subspecies currently recognised. In NSW, the race striatus was formerly distributed from the Namoi Valley area through the southern half of the Murray-Darling Basin. It is now currently known from only two disjunct localities. In central NSW, populations remain extant in Yathong Nature Reserve and surrounding areas of leasehold land. A second population occurs in south-western NSW in the Scotia Mallee west of the Darling River, including Tarawi NR, Scotia Sanctuary and adjoining properties. This population is contiguous with populations in adjoining mallee country in South Australia.

Habitat and ecology

  • Confined to areas with mature spinifex (Triodia irritans), usually in association with mallee eucalypts and sandy soils.
  • Is known to reoccuppy burnt vegetation 6 to 8 years following fire and prefers areas with large hummocks of spinifex which is greatest 25 to 40 years post-fire.
  • Feeds on the ground upon small invertebrates and seeds.
  • Nests are a substantial dome of interwoven grasses, bark and spinifex, well-hidden towards the top of a spinifex clump.
  • Usually recorded in pairs, though often in small parties, and first often detected by its call. Can be shy and difficult to observe, though may also be inquisitive and respond to observers, particularly during the breeding season.
