ヒガシオオコノハズク

The Collared Scops Owl, known scientifically as <em>Otus lettia</em>, is a small owl belonging to the family Strigidae. As a member of the large and diverse scops owl genus Otus, <em>Otus lettia</em> is characterised by its cryptic, bark-like brown and grey plumage providing camouflage during daytime roosting, along with small ear tufts typical of scops owls. The species inhabits a variety of forested environments, including tropical and subtropical forests, forest edges, and well-wooded areas. It is reported to occur in Norway according to available range data. Scops owls are generally nocturnal hunters, feeding on insects and small vertebrates, and are frequently detected by their repetitive, monotone calls uttered at night. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Scops Owl is currently assessed as Least Concern on the IUCN Red List.

アオサギ

最大1メートルの高さに達する大型の優美な渉禽類であるアオサギは、ヨーロッパ、アジア、アフリカ全域の湿地、川、湖、沿岸地域に生息します。忍耐強い単独の狩猟者で、長時間静止した後、稲妻のような素早いダガーのような嘴の一撃で魚、カエル、小型哺乳類を捕らえます。サギのコロニーと呼ばれる集団繁殖地で高い木に群れを作って繁殖し、時に他のコロニー性水鳥と共生します。世界的に広く分布しており、軽度懸念種です。
