ニッケイカギハシタイランチョウ

The cinnamon attila (Attila cinnamomeus) is a medium-sized flycatcher in the family Tyrannidae, found across the northern and western parts of the Amazon basin in South America, including Colombia, Venezuela, the Guianas, Trinidad, northern Brazil, and Ecuador. It inhabits the edges and interior of humid lowland and gallery forest, riverine thickets, and dense second growth from sea level to moderate elevations. The plumage is uniformly cinnamon-rufous, with a distinctive heavy bill, stout build, and upright, shrike-like posture characteristic of the attila group. Cinnamon attilas are predatory flycatchers, hunting large insects, small frogs, lizards, and occasionally birds' eggs or nestlings from conspicuous perches in the middle forest strata. The species is classified as Least Concern by the IUCN, with a wide northern Amazonian and Orinoco range and stable populations in intact humid forest. It is absent from Europe entirely; Norwegian database records are data entry errors reflecting incorrect geographic coordinates. The genus Attila comprises several Neotropical flycatchers with similar body form and hunting habits, often confused with each other in the field due to similar rufous coloration. The cinnamon attila's loud, varied calls are frequently heard in Amazonian and Orinoco riparian forest.

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。
