Physical description Click here for a physical description Dusky Grasswrens are grey-brown birds with long tails. Their cryptic plumage is dimorphic, i.e. males and females are slightly different. Both sexes have a dull-brown front and a darker, greyish-brown back. The head, chest and mantle are coarsely streaked grey. The wings and tail are dark greyish-brown. The only visible difference between the sexes is that males have unmarked flanks, whereas females have inconspicuous rufous flank spots. The irises of both sexes are dark-brown. The bill is grey; legs and feet are dark-grey. Juveniles have duller colours and less streaking than adults.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The overall distribution of the Dusky Grasswren is available HERE . Dusky Grasswrens are endemic to Australia. As is the case with all species of grasswrens, their overall distribution is complex, patchy and highly irregular. Some races also have very restricted ranges. This is mainly caused by the fact that grasswrens are rather poor fliers and individual populations, once separated, will not merge again, leading to a separation of the gene pools.Dusky Grasswrens have a limited range, stretching from the central NT, around Tennant Creek, to north-eastern SA and far-western WA, near the border of the 3 states, in a patchy distribution. Dusky Grasswrens have a strong preference for the ranges of central Australia, living mostly along rocky slopes in open woodland with Triodia ("Spinifex") undergrowth. They do not occur at the base of such rocky ridges, in gullies or valleys, even when offering good ground cover.

Sightings Click here for sighting information M. Eaton reports finding Dusky Grasswrens 15 km East of Alice Springs, NT, in October 2022. Another mob was found at Watarrka (Kings Canyon), George Gill Range, NT, in June 2023. All sighting and photographic information presented on this page has been kindly contributed by M. Eaton.
