A widespread antwren found from Colombia to southeast Brazil. Several subspecies occur throughout its range and are probably best recognized as at least two species. In general, males are grayish brown above and black below with a thick white eyebrow that connects with the white sides. Also note bold white spots on wings and tail. Females are variable; look for white eyebrow and wing spots. Southern birds are typically brighter tawny below, while northern birds are whitish below with dark streaks on the breast. Look for pairs foraging in the lower levels of dense shrubby woodland, often remaining fairly hidden and difficult to see clearly. Typically occurs in the lowlands up to around 1,000 m.
