チャボウシセッカ

The Chirping Cisticola (Cisticola pipiens) is a small, warbler-like bird belonging to the family Cisticolidae, one of the most diverse passerine families in the Old World. Members of the genus Cisticola are characterised by their cryptic brown-and-buff streaked plumage, slender bills adapted for gleaning insects from vegetation, and remarkably loud vocalisations relative to their diminutive size. The chirping cisticola inhabits wetland margins, reedbeds, and tall grasslands across sub-Saharan Africa, where it constructs intricate oval nests stitched together with plant fibres and spider silk. Like other cisticolas, it feeds primarily on small invertebrates including beetles, moths, and their larvae, foraging actively among dense grasses and sedges. The species undertakes short seasonal movements in response to rainfall patterns, following the flush of insect productivity that accompanies wet conditions. Males perform conspicuous song-flights during the breeding season, ascending above the grassland canopy before descending in a characteristic display. The IUCN classifies the Chirping Cisticola as Least Concern, reflecting its broad distribution and tolerance for a range of grassland and wetland habitats. Populations appear stable, though localised declines may occur where wetland drainage and agricultural conversion reduce available nesting sites.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
