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.
Campbell Island Shag
63 cm. Black and white pied shag; orange facial caruncles. Endemic to Campbell Island, New Zealand subantarctic. Vulnerable with total population of only a few hundred. Feeds on fish and invertebrates; nests on coastal cliff ledges in small colonies.
