An unusual white-eye that lacks white around the eye, but has a puffy white rump patch. The coloration is highly variable, with four morphs occupying largely separate distributions. Can be mostly brown, mostly gray, or a mix of the two. Found in virtually all habitats with woody vegetation on the island of Reunion. A conspicuous, sociable bird that is usually found in flocks. Vaguely similar to Reunion White-eye, but easily separated by the lack of a white eye-ring and the lack of olive-green in the plumage. The song is a repetitive series of warbling notes, typical of a white-eye. The calls are rattling and squealing notes.
