ハイイロモンキタイランチョウ

The cinereous mourner (Laniocera hypopyrra) is an unusual passerine bird in the family Tityridae, found throughout Amazonia and adjacent parts of northern South America, including Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, and the Guianas. It inhabits the interior of humid lowland and foothill forest, typically below 1,000 meters elevation, where it forages at middle and upper heights for large insects and occasional small fruits. The adult is a uniformly gray bird with orange-tipped wing coverts that are only visible at close range or in flight. Remarkable for its mimicry behavior, the nestling of the cinereous mourner closely mimics the coloration and slow swaying movements of the Megalopyge moth caterpillar—a toxic and venomous species—providing protection from predators during the vulnerable nestling stage. This constitutes one of the most striking documented cases of Batesian mimicry in a bird. The species is classified as Least Concern by the IUCN, with a large Amazonian range. It is restricted to South America and does not occur in Europe; Norwegian database records are erroneous. The cinereous mourner is typically seen singly or in pairs, and its secretive habits make it easily overlooked despite its relatively wide distribution.

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。
