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.

Little Black Cormorant

オーストラリアとニュージーランドの内陸水域や沿岸に生息するカワウで、嘴に溝がある特徴から名付けられた。河川や湖沼に広く生息し、魚を主に捕食する。
