Brief introduction: The Great Cormorant (Phalacrocorax carbo sinensis (Blumenbach, 1798)) is a widespread member of the cormorant family and is known by several different names around the world - the Great Black Comorant across the Northern Hemisphere, Black Shag in New Zealand, the Black Cormorant in Australia, and the Large Cormorant in India. It is a large black bird that can be distinguished from the Common Shag by its larger size, heavier build and thicker bill. They are mostly silent birds but can produce various guttural noises in their breeding colonies.
