Description
As its name suggests, the Great Cormorant is the largest species of cormorant in Australia. Its plumage is mostly black with a slight greenish sheen, visible only in good light. During the breeding season, Great Cormorants have orange-red skin on their faces and throats, but this fades to yellow at other times. They breed in colonies, often with other species of cormorants, herons, ibises and spoonbills, their platform-like stick nests built in trees in terrestrial wetlands, including floodwaters, or on coastal cliffs or offshore islands.
