About These Birds

カワセミ（Alcedo atthis）— ユーラシアおよびアフリカに広く分布する鮮やかな青橙色の鳥。川や池のほとりで魚を捕食する。
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.
