Range DescriptionThis species is found in the Kimberley region of northern Western Australia, Australia, from Admiralty Gulf south through the Mitchell Plateau, Roe, Prince Regent, Glenelg and upper Charnley rivers, to Manning Creek. Much of its range occurs in Aboriginal reserves, vacant crown land or conservation reserves including the Prince Regent River Reserve which covers c.6,340 km2. This species was once considered scarce, but this was primarily because few ornithologists visited its remote, largely inaccessible habitat. It has since been reported to be moderately common to common e.g. 16 pairs counted in a 2 km transect along a creek in sandstone near Mertens Falls (Johnstone and Storr 2004), with a total population of 15,000 mature individuals postulated (Garnett et al. 2011). It may have been extirpated from Manning Creek by fire, and an increase in large scale anthropogenic fires late in the dry season is inferred to be driving a decline in the range and population.
