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.

Bicoloured White-eye

The Bicoloured White-eye is a small white-eye endemic to the island of Seram in the Moluccas, Indonesia. It has greyish upperparts and pale underparts with the characteristic white eye-ring. It forages in forest canopy for insects, nectar, and small fruits.
