The Great Cormorant is the largest of the cormorants. It is mainly black, but has a yellow throat patch and facial skin. It has a white patch on the lower body above the legs when breeding.
They are sociable birds, nesting in colonies along inland waterways and wetlands, often with other cormorants, herons, ibises and spoonbills. They swim and pursue their prey underwater by using their feet rather than their wings. They can breed at any time, as long as food is available. They feed mainly on fish with some crustaceans, insects and frogs.
