Laysan Albatross (diomedea Immutabilis): Species Accounts
Physical characteristics: Laysan albatrosses have a wingspan of 6.4 to 6.7 feet (1.95 to 2.03 meters) and weigh 5.3 to 9.0 pounds (2.4 to 4.1 kilograms). They are white in color with black patches at the wrist and elbow. There is a gray patch around the eyes and cheeks. The bill is yellowish orange at the base and fades into pink with a black tip.
Geographic range: Laysan albatrosses live almost exclusively in the Hawaiian Islands. Smaller populations live on the Bonin Islands in the west Pacific Ocean and in the eastern Pacific at Islas Guadalupe, Benedicto, and Clarion.
Habitat: Laysan albatrosses spend most of their time on the water, moving onto land only to breed.
Diet: Squid is the main staple of the Laysan albatrosses' diet, but they also eat fish eggs, fish, and crustaceans, marine life having no backbone. They are not known to follow fishing vessels as is the habit of other albatross species.
Behavior and reproduction: Laysan albatrosses have a wider range of displays than other albatrosses, and their communicative sounds have are distinct from those of other families. The nest is a hole in the ground that is built up around the rim using sand and other available debris. They lay one egg between the end of November and the end of December. Incubation lasts an average of sixty-four days, with parents taking turns, sometimes up to three weeks at a time.
Laysan albatrosses and people: The Laysan albatross is nicknamed the "gooney" and is a common sight in the countries surrounding the north Pacific Ocean.
Conservation status: The world population of Laysan albatrosses is around 607,000 pairs, although some colonies are decreasing due to commercial fishing and high levels of contaminants as well as plastic trash in the water. The species is considered Vulnerable, facing a high risk of extinction in the wild. ∎
