Great Cormorant

The great cormorant is a large and versatile seabird found across much of the world, from the coasts of Europe and Asia to Africa and Australia. With their glossy black plumage, long necks, and hooked beaks, these birds are adept hunters, capable of diving to depths of up to 10 meters (33 feet) to catch fish.

Great cormorants are highly social and often seen roosting or fishing in large groups. They are excellent swimmers, using their webbed feet to propel themselves underwater while chasing prey. Once they surface, they are often observed spreading their wings to dry, as their feathers are not fully waterproof—a trait that enhances their diving efficiency.

These birds inhabit coastal waters, lakes, and rivers, nesting in colonies on cliffs, trees, or rocky islets. Their adaptability allows them to thrive in a variety of environments, but they are also sensitive to pollution and habitat destruction.

In some regions, great cormorants have a long history of coexistence with humans. Traditional fishermen in parts of Asia have used trained cormorants to catch fish, a practice dating back centuries. However, conflicts sometimes arise, as cormorants are seen as competitors for fish stocks. Conservation efforts are needed to balance their ecological importance with human interests.
