White-browed Treecreeper Climacteris affinis

Small bird with rather massive feet and pale eyebrow, most often seen running up and down the sides of trees in arid and semi-arid woodlands, especially old-growth mulga forest (unlikely to be found in eucalypts along rivers). Predominantly grayish brown with bold pale streaking on dark belly. In flight, note bold tan wingbars. Compare larger, darker Brown Treecreeper, which has less obvious streaking behind the ear and on belly and tends to spend more time on the ground. Call is a repetitive, insect-like piping.
