Collared Crow

Corvus pectoralis, the Collared Crow, is a large corvid in the family Corvidae. This species is classified as Vulnerable on the IUCN Red List, indicating a high risk of extinction under current conditions. It is documented in Taiwan and is also found in eastern China, inhabiting lowland areas including river valleys, agricultural land, and coastal regions. The Collared Crow is named for the distinctive white collar that separates its black head and upperparts from its white underparts. Members of the genus Corvus are known for high intelligence, omnivorous diets, and adaptability to human-modified landscapes. Despite this adaptability, Corvus pectoralis has experienced significant population declines, likely attributable to habitat loss, hunting pressure, and possibly competition with other corvids. Diet, population estimates, and biological measurements including average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. Its Vulnerable status underscores the need for targeted conservation actions within its range.

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。
