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-capped Speirops
The Black-capped Speirops is a white-eye endemic to Annobon Island off the coast of Equatorial Guinea in the Gulf of Guinea, with a distinctive black cap and greenish body plumage. It inhabits forest canopy and edges on this small oceanic island. It feeds on nectar, berries, and small insects. Its restricted island range makes it potentially vulnerable to introduced predators and habitat change.
