About These Birds
European Robin
イギリスの非公式の国鳥で、縄張り意識が強く、一年中さえずる。民話では鳥の中の特別な地位を持つ。
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.
