About These Birds
Common Ostrich
ダチョウ（Struthio camelus）— 世界最大の鳥でアフリカのサバンナに生息する。飛べないが時速70kmで走ることができ、世界最大の卵を産む。
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.
