About These Birds
Barn Owl
メンフクロウはあらゆるフクロウの中で最も非対称な耳を持ち、動物界最高の聴覚的方向定位能力を誇る。完全な暗闇の中でも音だけで獲物を捕まえることができる。特徴的なハート形の顔は放物線状の皿として機能し、ずれた両耳に音を集める。
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
