The largest flying bird in the world by wingspan is the wandering albatross (Diomedea exulans), with a wingspan of up to 11 feet (3.4 meters). These magnificent birds have a range of up to 10,000 miles (16,000 kilometers), and spend most of their time over open water, feeding on fish, cephalopods, and crustaceans. Wandering albatrosses are known for their distinctive mating dance and their ability to travel enormous distances without flapping their wings. These birds are found in the Southern Ocean and are considered vulnerable to threats such as longline fishing, climate change, and plastic pollution.
