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.
Annobon White-eye
The Annobon White-eye is a small passerine endemic to Annobón Island, weighing just 11 grams with a wingspan of about 13 cm. Like other white-eyes, it likely forages actively for nectar and small invertebrates in forest vegetation. Its compact build and island habitat make it a distinctive member of the Zosteropidae family.
