ムナグロマユシトド

The Collared Warbling Finch, known scientifically as <em>Poospiza hispaniolensis</em>, is a small passerine bird belonging to the family Thraupidae, the tanagers and allies. <em>Poospiza hispaniolensis</em> is characterised by its neatly patterned plumage, which typically features contrasting black-and-white head markings and a distinctive collar or chest band element consistent with other members of the warbling finch group. The species typically inhabits scrubby, arid, and semi-arid environments, foraging for seeds and small invertebrates in low vegetation and on the ground. It is reported to occur in Ecuador and Norway. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Warbling Finch is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is stable without significant conservation concerns.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
