A small green songbird with a bold white eye-ring, a black forehead, and whitish underparts except for a yellow throat and undertail. Juveniles duller, with less black on forehead. Found in groups, often within mixed-species flocks, in forests, edges, and cultivated areas in lowlands and foothills. Separated from Lemon-bellied White-eye by whitish belly, and from Warbling and Sulawesi White-eyes by black forehead on Black-crowned White-eye. Song variable, comprising short, high-pitched warbles. Also gives chattering and twittering notes as well as “tzew” and repetitive “titititititit” trill calls.
