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.

80 cm. Large; dark brown with pale yellow gape and facial skin. Breeds on islands in the Persian Gulf, Gulf of Oman, and Red Sea. Vulnerable; faces threats from oil spills, human disturbance, and overfishing. Feeds on fish in warm Arabian Sea; colonial nester on flat, barren islands.
