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.
Black-crowned White-eye
The Black-crowned White-eye is a small, greenish white-eye found on several islands in the Philippines, Sulawesi region, and the Moluccas, with a distinctive black forehead and crown contrasting with yellowish-green body plumage. It inhabits forest canopy, forest edges, and gardens, feeding on nectar, small insects, and berries. Island subspecies show some variation in extent of the black crown.
