A gray-and-white songbird with a diagnostic head pattern. Dark olive above and clean white below, with dark cheeks that contrast with the conspicuous pale eye and a white forehead bleeding into dark speckles on the crown. Juveniles show a plain buff forehead and crown. Found singly or in pairs in understory of forest and forest edge in lowlands and foothills, frequenting mixed-species flocks. Confined to the Lesser Sundas. Calls include soft “chup” and weak “pew” notes. Striking, melodious warbling song is punctuated with repeated clear trills and staccato “wit-wit-wit” phrases.
