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.
Spectacled Cormorant
Extinct; last recorded in 1850 on Bering Island. Very large; dark green-black with white spectacle marks. Flightless or near-flightless. Endemic to Bering Sea islands; exterminated within decades of discovery by Russian fur traders hunting for food. One of the few recently extinct cormorants.
