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.
Rock Shag
60–66 cm. Black above; white below; vivid red-orange caruncles at bill base in breeding. Breeds coasts and islands of southern Chile, Argentina, and Falkland Islands. Feeds on fish in cold sub-Antarctic inshore waters. Nest on cliff ledges in small colonies; resident.
