オグロセッカ

The cloud-scraping cisticola (Cisticola dambo) is a small passerine bird in the family Cisticolidae native to sub-Saharan Africa, found in seasonally flooded grasslands, dambos (seasonal wetland grasslands), and moist montane meadows from the Democratic Republic of Congo and Tanzania south through Zambia, Malawi, and Zimbabwe. Males perform spectacular, high-altitude aerial song flights, ascending so high they seem to disappear into the clouds — giving the species its evocative common name. The plumage is cryptically streaked brown and buff, with males showing a more defined facial pattern during the breeding season. Like other cisticolas, it constructs an elaborate woven grass nest low in grass tussocks. The cloud-scraping cisticola is highly dependent on seasonally inundated grasslands and dambos, habitats increasingly threatened by drainage for agriculture, overgrazing, and invasion of exotic plant species. Population declines in parts of its range are attributed to the loss and degradation of dambo habitats across the miombo woodland regions of central Africa, where these seasonal wetlands support exceptional biodiversity including numerous highly specialized bird species.

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。
