Colombian Chachalaca

<em>Ortalis columbiana</em>, commonly known as the Colombian Chachalaca, is a bird species belonging to the genus <em>Ortalis</em> within the family Cracidae, a group of large, chicken-like birds native to the Americas. This species is assessed as Least Concern by major conservation bodies, indicating stable populations that are not presently at elevated extinction risk. It has been documented in Colombia, its primary native range, and records also note an occurrence in Norway, likely reflecting captive or introduced individuals rather than a natural wild population. The Colombian Chachalaca inhabits various aerial, terrestrial, and aquatic-adjacent environments, typically favoring forest edges, dense scrubland, and gallery forests along watercourses. Chachalacas are primarily frugivorous, supplementing their diet with leaves, flowers, and small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The species is known for its loud, raucous calls, particularly at dawn and dusk, which are a characteristic feature of its habitat soundscapes. Habitat protection in Colombia is important for maintaining healthy populations.

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。
