カオグロアメリカムシクイ

<em>Geothlypis trichas</em>, the common yellowthroat, is a small New World warbler in the family Parulidae. It is one of the most abundant and widespread warblers in North America, breeding across most of the continent from Alaska and Canada south through the United States and into Mexico and Central America. The species is strongly associated with dense, low-growing vegetation near water, including freshwater marshes, reed beds, shrubby wetlands, and riparian thickets. Adult males are distinctively marked with a bright yellow throat and breast, olive-green upperparts, and a bold black facial mask bordered by white above, making them among the most recognizable North American songbirds. Females and immatures are more subdued, lacking the black mask. Biological traits such as precise average lifespan and body weight remain variable; adults typically weigh 9–10 g and live 1–3 years on average in the wild. The species feeds primarily on insects and spiders gleaned from dense vegetation. It builds a well-concealed domed or cup nest low in vegetation near water. <em>Geothlypis trichas</em> is assessed as Least Concern, reflecting its vast range and large, broadly stable population.

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。
