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.
South Georgia Shag
62 cm. Black and white; orange caruncles. Endemic to South Georgia and surrounding subantarctic islands. Feeds on fish in cold, productive South Georgia waters. Colonial nester on cliff ledges; closely related to Imperial Shag complex. Resident; does not migrate far from islands.
