Physical description Click here for a physical description Kalkadoon Grasswrens are small, grey-brown birds with long tails. Their cryptic plumage is dimorphic, i.e. males and females are slightly different. Both sexes have a dark-grey head and back, finely streaked white and rufous. The chest shows a stronger hint of rufous streaking. Upperwings and tail are dark grey-brown, with white streaking on the wing coverts. Males have a grey belly and flanks, while females have rufous flanks and a rufous-grey belly. Juveniles are similar to females, but with fainter white streaking and a pale base of the bill.

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 Kalkadoon Grasswren is available HERE . Kalkadoon 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.This species, which was formerly considered to be a race of the Dusky Grasswren (not described here yet), has a very restricted range. Kalkadoon Grasswrens are only found in the Selwyn Range system, an area around the deserted mining town of Ballara, QLD, ranging from Mount Isa to Cloncurry and up to about 100 km to the North and South from a line connecting those two towns. Kalkadoon Grasswrens have a strong preference for hills and rocky slopes of the Selwyn Ranges covered with Triodia ("Spinifex") grass.
