The Laysan rail or Laysan crake is an extinct species flightless rail endemic to the Northwest Hawaiian Island of Laysan. This small island was and still is an important seabird colony, and sustained a number of endemic species, including the rail. It became extinct due to habitat loss by domestic rabbits, and the introduction of rats to Midway during the Second World War.
Region
Northwestern Hawaiian Islands
Typical Environment
Historically confined to Laysan Island, it occupied dense coastal shrubs, bunchgrass stands, sand dunes, and the margins of the island’s hypersaline lake. It foraged extensively within seabird colonies, taking advantage of invertebrates associated with nesting birds and carrion. A small, human-assisted population persisted for a time on Midway Atoll before being wiped out by rats during the Second World War. The species was entirely terrestrial and avoided open, exposed areas when possible.

The Laysan rail was a tiny, flightless rail restricted to Laysan Island in the Northwestern Hawaiian Islands. It became extinct after habitat devastation by introduced rabbits on Laysan and the later introduction of rats to Midway Atoll, where a translocated population briefly survived. Remarkably tame, it often foraged around seabird colonies and human camps for insects and scraps. Its loss is a classic example of island vulnerability to invasive species.

Temperament
tame and inquisitive but wary in open spaces
Flight Pattern
flightless; prefers running with short fluttering hops
Social Behavior
Typically seen singly or in pairs, it nested on the ground in dense vegetation. Pairs likely formed monogamous bonds during the breeding season. Both parents are thought to have attended the brood, guiding chicks through cover while foraging near seabird colonies.
Migratory Pattern
Resident
Song Description
Vocalizations were a mix of soft clucks and rapid ticking notes, with occasional rasping squeaks. Calls carried through shrub thickets and were used to maintain contact between mates and signal alarm.
