Welcome to featured Wiki of the Day where we read the summary of the featured Wikipedia article every day.
The featured article for Tuesday, 30 April 2024 is Inaccessible Island rail.
The Inaccessible Island rail (Laterallus rogersi) is a small bird of the rail family, Rallidae. Endemic to Inaccessible Island in the Tristan Archipelago in the isolated south Atlantic, it is the smallest extant flightless bird in the world. The species was described by physician Percy Lowe in 1923 but had first come to the attention of scientists 50 years earlier. The Inaccessible Island rail's affinities and origin were a long-standing mystery; in 2018 its closest relative was identified as the South American dot-winged crake (Porzana spiloptera), and it was decided that both species are best classified in the genus Laterallus.
A small species, the Inaccessible Island rail has brown plumage, black bill and feet, and adults have a red eye. It occupies most habitats on Inaccessible Island, from the beaches to the central plateau, feeding on a variety of small invertebrates and also some plant matter. Pairs are territorial and monogamous, with both parents being responsible for incubating the eggs and raising the chicks. Its adaptations to living on a tiny island at high densities include low base metabolic rates, small clutch sizes, and flightlessness.
Unlike many other oceanic islands, Inaccessible Island has remained free from introduced predators, allowing this species to flourish while many other flightless birds, particularly flightless rails, have gone extinct. The species is nevertheless considered vulnerable by the International Union for Conservation of Nature (IUCN), due to its single small population, which would be threatened by the accidental introduction of mammalian predators such as rats or cats.
