ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

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.
