The Wandering Albatrosses, Diomedea exulans, are very large birds and have the largest wingspan of any other bird, with some uncorroborated reports of 13 feet! The average wingspan is 8.2-11.5 feet, and they weigh nearly 25 pounds….almost 3X that of the Bald Eagle (9.1 pounds)! Some Wanderers have been measured with bill lengths greater than 7 inches!
