Biak White-eye Zosterops mysorensis

A small bird of forest on Biak Island where it is the only white-eye. Olive-green head and back, yellow under the base of the tail, dark gray face, pale gray underparts with whitish throat and belly. Note the lack of an eye-ring. Sometimes associates with other small birds. Similar size to Island Leaf-Warbler and Biak Gerygone, but Biak White-eye has grayish rather than yellow underparts. Voice, an up-and-down, high-pitch, warbling song and a rather sharp, descending “meuu” call.
