シナモンコビトドリモドキ

The cinnamon-breasted tody-tyrant (Hemitriccus cinnamomeipectus) is a tiny insectivorous bird in the family Tyrannidae, endemic to a small area of highland forest in Ecuador and possibly adjacent Peru. It inhabits the undergrowth and bamboo thickets of humid montane forest on the eastern Andean slopes at elevations between approximately 1,500 and 2,200 meters. The species is named for the rich cinnamon-rufous coloration of its breast, which contrasts with its gray head and olive-green upperparts. Like other tody-tyrants, it is a compact, short-billed flycatcher that forages in dense, low vegetation for small insects and spiders. The cinnamon-breasted tody-tyrant is classified as Least Concern by the IUCN. However, given its very limited geographic range on the eastern Andean slopes of Ecuador, it is considered a species of conservation interest due to vulnerability to cloud forest habitat loss in this region. Ecuador's eastern Andes contain some of the world's highest concentrations of endemic bird species and face ongoing deforestation pressure from agricultural expansion and road-building. Hemitriccus tody-tyrants are among the most difficult flycatchers to identify in the field due to their small size, secretive habits, and similar appearances across the group. Vocalizations are often the primary means of detection and identification.

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。
