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.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
