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.
Little Black Cormorant
55–65 cm. All-black; glossy green-blue; bare black facial skin. Widespread across Australia, New Zealand, and Southeast Asia in freshwater and marine environments. Highly gregarious; nests colonially in trees. Feeds on fish by pursuit-diving; often seen drying wings on posts.
