About These Birds
ハクトウワシ
ハクトウワシはアメリカ合衆国の国鳥で国の象徴である。DDT農薬使用により一度は絶滅の危機に瀕したが、見事な回復を遂げ、2007年に絶滅危惧種リストから外された。これらの力強い猛禽類は、2トンを超えるものもある鳥類最大の木の巣を作る。
Southern Cassowary
The southern cassowary is often called the most dangerous bird in the world due to its powerful legs and dagger-like inner claw that can reach 12 cm in length. Despite this reputation, cassowaries are vital rainforest keystone species, dispersing seeds of plants that no other animal can. The purpose of their distinctive casque remains debated.
