Batis fratrum lives on the coastal plain of southeastern Africa. Males have grey backs and a white wing-bar; females have a narrow pale eyebrow and rufous wing-bar. It searches for insects in forest understory.
Males have grey foreheads, crowns, napes, and backs, blackish wings with a white wing-bar, white throat, pale rufous breast, and yellow eyes. Females have a narrow whitish eyebrow, rufous wing-bar and throat, and orange eyes.
It uses the understory of coastal evergreen forest and thicket, usually singly or in pairs, and forages for insects below the canopy. The southern African atlas also describes a preference for coastal closed-canopy forest and thicket understory.
