マルハシミツドリ

The cinereous conebill (Conirostrum cinereum) is a small, active bird in the family Thraupidae, found across the Andes from Colombia and Ecuador south to northern Chile and northwestern Argentina. It inhabits open scrubby habitats, Polylepis woodland, shrubby grassland, and the margins of montane forest at elevations typically between 1,500 and 4,500 meters, making it one of the highest-elevation conebills. The plumage is gray above and pale below, with a distinctive conical bill adapted for probing flowers and gleaning insects. The cinereous conebill is classified as Least Concern by the IUCN, with a wide Andean distribution and populations considered stable. It is a common component of high-Andean bird communities, often joining mixed-species foraging flocks that exploit nectar and insects across a range of shrubby montane habitats. Its range is entirely within the Andes of western South America, and any database record listing Norway is a data entry artifact. The conebills (Conirostrum) are a genus of small tanagers specialized for exploiting flowers and bark crevices, with several species distributed across Andean and Amazonian habitats. Conservation of Andean montane vegetation, including the critically threatened Polylepis woodland ecosystem, is important for this and many co-occurring highland specialists.

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。
