ハジロコチドリ

ハジロコチドリ（Charadrius hiaticula）はIUCNレッドリストで絶滅危惧IA類（CR）に分類されている。著しい個体数減少と生息地喪失により、野生での絶滅リスクが非常に高い。

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
