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.
Bioko Speirops
The Bioko Speirops is a vulnerable white-eye endemic to the montane forests of Bioko Island, Equatorial Guinea. It has brown-olive plumage without the typical white eye-ring of most white-eyes. It forages in forest canopy for insects, nectar, and berries, and is threatened by habitat loss and its very restricted island range.
