A very unusual large and chunky warbler with a white eyebrow and throat, streaked breast, and rufous belly. Found on and around rocks within arid savanna. Usually seen singly or in pairs. Can be skulky and inconspicuous, though sometimes sits out and sings from the top of big rocks. The beautiful song is an accelerating and descending series of warbles. The call is a harsh ratchet. Difficult to confuse with any other species within its small range.
