ハイイロイワタイランチョウ

The cinereous ground tyrant (Muscisaxicola cinereus) is a small flycatcher in the family Tyrannidae, found in the high Andes and Patagonian grasslands of South America, with a range spanning Chile, Argentina, Bolivia, and Peru. It inhabits open, barren, or sparsely vegetated habitats such as high-altitude puna grassland, rocky Andean plateaus, rocky coastal grassland, and steppe vegetation, typically at elevations from 1,000 meters to above 4,500 meters. Like other ground tyrants, it forages on the ground for insects and small invertebrates, often running and pausing rather than perching. The plumage is uniform gray to brownish-gray with a slightly paler underside. The cinereous ground tyrant is classified as Least Concern by the IUCN, with a wide South American range and stable populations. Ground tyrants of the genus Muscisaxicola represent a fascinating adaptive radiation into high-altitude open habitats across the Andes and southern South America. This species is entirely restricted to South America and is absent from Europe; any database record citing Norway is incorrect. Andean grassland habitats face increasing pressure from overgrazing, burning, and climate-driven changes in vegetation, but the cinereous ground tyrant's wide range and tolerance of degraded habitats suggest resilience.

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。
