Small bird of open arid shrubland and grasslands. Pale brown above, whitish below, with distinct pale supercilium, faint chest streaking, and long, cocked tail. Forages quietly on the ground or in thick vegetation, where difficult to see. Most easily observed when males sing in spring, as they perch up in the vegetation. Similar to Western Fieldwren but no range overlap. Compare Shy Heathwren, which has a white wing spot and darker legs.
