Miombo Wren-Warbler Calamonastes undosus

Long-tailed brownish warbler. The northern subspecies has gray-brown underparts with vague barring, while the southern subspecies has white underparts with clean dark barring. Found in broadleaved woodland and moist savanna. Often raises its tail in wren-like fashion. Northern birds give a repeated cheeping note; southern birds give a metallic, repeated, 3-note call. Northern birds are less distinctive but can still be recognized by their shape and the bars on their underparts.
