About These Birds
Emperor Penguin
最大・最重量のペンギンで、南極の-60℃の厳しい環境下で繁殖する。オスが卵を抱いて越冬する。
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.
