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.

European Shag

体長68〜78 cm、翼幅95〜110 cm。光沢のある緑色を帯びた全黒色；繁殖期には短い直立した冠羽；黄色い口角。厳密に海洋性で、西ヨーロッパと地中海の岩礁海岸に繁殖。澄んだ沿岸水域で潜水して魚を捕食。絶滅危惧種；石油流出と乱獲が脅威。
