This seabird exhibits considerable versatility in habitat preference, with some populations thriving in the saline environments of the North Atlantic, while others are more commonly found in freshwater lakes and rivers across the globe.
These large, solidly built birds are characterized by their dark plumage, long necks, and hooked bills, designed for an aquatic lifestyle centered around fishing. Great Cormorants are highly skilled in underwater hunting, using their webbed feet to propel themselves and their tail as a rudder, allowing for agile pursuit of prey beneath the water’s surface. They can dive to considerable depths and remain underwater for up to a minute, though their usual dives last only around 20-30 seconds.
Cormorants have been observed to forage alone or in groups, and their gregarious nature extends to their breeding habits. They nest in colonies that can number in the hundreds, sometimes even thousands, choosing cliff faces, trees, or ground sites near water to build their bulky nests made of sticks and seaweed. These nesting colonies become bustling communities, with each pair vigorously defending their immediate nesting area.
The Great Cormorant’s diet is predominantly fish, and their fishing efficiency has made them the subject of both admiration and conflict with humans. In some parts of Asia, especially China and Japan, fishermen have trained cormorants for centuries to catch fish, a practice known as cormorant fishing. The birds are fitted with a ring around their neck to prevent them from swallowing larger fish, which the fisherman retrieves.
