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.

ヒバリ

ヒバリ（Alauda arvensis）は、飛翔中に歌う複雑で美しい声でヨーロッパの文学と詩に称えられてきました。ヨーロッパとアジア全域の開けた農地、草地、荒野の上空を数百メートルも垂直に舞い上がりながら、最長1時間にわたって途切れなく歌い続けます。雄は700種類以上の独特なさえずりを発することができます。かつてヨーロッパの農地で非常に多かったヒバリの個体数は、農業の集約化により1970年代から70%以上減少しています。
