About These Birds
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.
Hawfinch
シメはヨーロッパの鳥の中で体の大きさに対して最も強力なくちばしを持ち、27〜43 kgの力でサクランボの種を割ることができる。その特徴的な外見にもかかわらず、著名なほど恥ずかしがり屋で観察が難しい。種割り時に発生する巨大な力を吸収するための頭骨の特殊な適応を持つ。
