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.

63 cm. Black above; white below; orange-yellow caruncles; blue eye-ring. Endemic to Crozet Islands, southern Indian Ocean. Vulnerable with small total population. Feeds on fish and invertebrates in cold Crozet Island waters. Colonial nester on coastal cliffs.
