The Laysan albatross is named for one of its largest breeding colonies in the Hawaiian Islands. Though these birds have wingspans of nearly 7 feet (two meters), they are actually relatively small compared to other albatrosses. Laysan albatrosses are known for their clumsiness on land but their incredible grace in the air.

As in all seabirds, Laysan albatrosses nest on land.  Essentially all individuals of this species nest in large colonies of thousands of breeding pairs in the Northwest Hawaiian Islands, though previously unknown colonies have recently been observed on small islands off the coasts of Mexico and Japan.  These birds form strong pair bonds and generally mate for life, with only a small percentage of cheating.  Most birds return to breed as part of the colonies where they hatched.  Laysan albatrosses breed every year or every other year, starting when they are 8 or 9 years old.  Incubating the egg and caring for the chick require a significant commitment of time (at least 225 days), so these birds spend much of the year travelling back and forth between their nesting sites and feeding trips, often leaving the chick unattended.  After the chick leaves the colony, it does not return for 3 or 4 years, spending that time growing and feeding across the north Pacific.  Even when it returns, it does not mate for several years and instead spends time cultivating a pair bond.  The sex ratio of these birds can be quite skewed, with significantly more females.  In those instances, females may form same sex bonds and successfully raise chicks fathered by males that have cheated on their own mates. 

When feeding, Laysan albatrosses range across most of the north Pacific Ocean.  They primarily eat pelagic squids but also take fishes and other pelagic invertebrates.  Adult Laysan albatrosses have no natural predators, but invasive cats and dogs kill both juveniles and adults in nesting colonies.  Historically, hunting reduced population size in some places, and accidental capture in fisheries targeting pelagic squids and fishes continues to threaten these birds.  As a result, scientists consider the species to be near threatened with extinction.
