About These Birds
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
Biak White-eye
The Biak White-eye is a near-threatened small passerine endemic to Biak Island in West Papua, Indonesia. It has olive-green plumage with the characteristic white eye-ring of white-eyes. It forages in forest canopy and edges for insects, nectar, and small fruits, and is restricted to its small island range.
