Laysan albatross
Laysan albatross is a large, abundant seabird whose breeding range is centered in Hawaii.
Like all albatrosses, they are accomplished fliers using dynamic soaring to cover great distances.
They mainly feed at night and often far from breeding colonies.
According to the National Oceanic and Atmospheric Administration, the average lifespan of a Laysan albatross is typically around 68 years.
Laysan albatross matures slowly, starting to breed at three or four years old, but typically achieving successful breeding only at eight or nine years of age.
They nest in colonies, have long-term pair bonds and high site fidelity.
They lay only one egg per season and the egg is incubated by both the parents in turn.
IUCN Red list: Near Threatened
