Description

The Grey Grasswren is a very distinctive, pale grasswren with a striking black and white pattern on the head.

Distribution

Confined to areas dominated by Lignum (Muehlenbeckia florulenta) along tributaries of the Diamantina River and Coopers Creek in the Lake Eyre drainage basin, and along the lower Bulloo River. In NSW the Grey Grasswren is recorded from Caryapundy Swamp above the Bulloo Overflow (Bulloorine).

Habitat and ecology

  • Shelters, roosts, nests and feeds almost entirely within dense, tall Lignum, with associated Sandhill Canegrass (Zygochloa paradoxa) and sedges in swamps, overflow channels and flood pans; may be forced into stands of Canegrass or Oldman Saltbush growing on surrounding sand dunes when the areas of Lignum become flooded.
  • Although thought to be largely sedentary, and in territorial pairs when breeding, groups of between 15 and 40 individuals forage together outside the breeding season; other movements may occur, associated with floods and droughts.
  • Builds loose and bulky grass nest in Lignum or Canegrass, between 30 and 75 cm above the ground.
  • Insect larvae comprise the bulk of its diet, but mature insects and at times water snails are also eaten.
