ハシグロアビ

<em>Gavia immer</em>, the common loon or great northern diver, is a large aquatic bird in the family Gaviidae, known for its haunting, yodeling calls across northern lakes. It is found in Belgium, Denmark, Norway, Sweden, and the United States, breeding on freshwater lakes in boreal and subarctic regions and wintering along marine coastlines. The common loon is adept in aerial, terrestrial, and aquatic environments, though it is most highly specialized for diving, using its strong feet positioned far back on its body to pursue fish underwater. It typically feeds on fish, supplemented by crustaceans and aquatic invertebrates. Its striking summer plumage features a black-and-white checkered back and a deep black head with a characteristic white necklace pattern. The species has not been evaluated for IUCN conservation status. Common loons require clear, fish-rich lakes for successful breeding and are sensitive to water quality degradation and human disturbance at nesting sites. Their distinctive calls are emblematic of wilderness in North America and Scandinavia.

giraffe

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
