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.
Bank Cormorant
南アフリカとナミビアの沿岸岩礁に限定して生息するカワウで、バンクシーカワウとも呼ばれる。非常に限られた分布域に生息し、漁業との競合が懸念されている。
