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.
