シロエリハッカ

The Collared Myna, known scientifically as <em>Acridotheres albocinctus</em>, is a passerine bird belonging to the starling family Sturnidae. <em>Acridotheres albocinctus</em> is recognised by its contrasting plumage, which typically features a dark body with a distinct white collar or band — a feature reflected in both its common and scientific names. As a member of the myna genus Acridotheres, this species generally inhabits open woodland, grassland edges, and areas associated with human settlement, where it forages on the ground for invertebrates, fruits, and seeds. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Myna is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is considered stable without significant conservation concerns at this time.

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。
