The Inaccessible Island rail (Laterallus rogersi) is a bird found only on Inaccessible Island in the South Atlantic Tristan archipelago. This rail, the smallest extant flightless bird, was described by physician Percy Lowe in 1923. The adult has brown plumage, a black bill, black feet, and red eyes. It occupies most habitats on the island, from the beaches to the central plateau, feeding on a variety of small invertebrates and some plant matter. Pairs are territorial and monogamous; both parents incubate the eggs and raise the chicks. The rail's adaptations to living on a tiny island at high densities include a low basal metabolic rate, 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 rails have gone extinct. The species is nevertheless considered vulnerable, due to the danger of a single catastrophe wiping out the small, isolated population. ( Full article...)
