ソロモンオウギビタキ

Cockerell's fantail (Rhipidura cockerelli) is a lively, medium-sized flycatcher in the family Rhipiduridae, endemic to the Solomon Islands archipelago in the southwestern Pacific Ocean. Like other fantails, it is characterised by its habit of fanning and cocking its long tail while foraging aerially and among vegetation for small flying insects and other arthropods. The species occupies primary and mature secondary lowland and hill forest on several islands within the Solomon group, where it typically inhabits the middle and lower forest strata, often joining mixed-species foraging flocks. Males and females are similarly plumaged in shades of rufous, brown, and black, with the distinctive white brow stripe common to many Solomon Islands fantails. Rhipidura cockerelli is classified as Least Concern by the IUCN, reflecting adequate forest cover across much of its range and the relative remoteness of many of the islands it inhabits. However, growing pressure from logging, agricultural conversion, and human settlement in the Solomon Islands poses potential longer-term risks to forest-dependent species like this fantail. The species has no presence in Norway; database listings to that effect represent a data artifact. Its distribution is confined entirely to the Solomon Islands chain. The species was named after the British entomologist and naturalist T.D.A. Cockerell, who contributed extensively to natural history collections from the Pacific during the late nineteenth and early twentieth centuries.

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。
