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.

Crowned Cormorant

南アフリカ西岸固有のクラウンドコーモラント。体長50〜55cm。黒色の体に赤い喉嚢と小さな冠羽が特徴的。岩礁の多い海岸線に生息し、魚を潜水して捕食する。絶滅危惧種。
