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
68–78 cm, wingspan 95–110 cm. All-black with glossy green; short erect crest in breeding; yellow gape. Strictly marine; breeds on rocky coasts of western Europe and Mediterranean. Feeds on fish by diving in clear coastal waters. Vulnerable; threatened by oil spills and overfishing.
