カオグロオナガ

The Collared Treepie, known scientifically as <em>Dendrocitta frontalis</em>, is a corvid belonging to the family Corvidae. <em>Dendrocitta frontalis</em> is a member of the treepie group — arboreal corvids found in Asian forests — and is characterised by its long graduated tail, colourful plumage, and bold behaviour typical of the crow family. The species typically inhabits dense subtropical and tropical montane forest environments, where it forages in the canopy and mid-storey for fruits, insects, eggs, and other food items. It is reported to occur in Norway according to available range data. Treepies are generally noisy and active birds, moving through forest with rapid hops and flights. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Treepie 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。
