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.
Pygmy Cormorant
45–55 cm. Small; dark brown with chestnut head and neck in breeding; pale yellow throat. Resident across eastern Europe, Middle East, and Central Asia in freshwater lakes and rivers. Vulnerable; declining due to wetland degradation. Feeds on small fish by diving.
