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.
Pelagic Cormorant
63–73 cm. Small, slim cormorant; entirely glossy green-black; narrow bill; slender neck. Breeds along Pacific coasts from Baja California to NE Russia on rocky cliffs. Feeds on small fish in kelp beds. Least gregarious North Pacific cormorant; nests in small scattered groups.
