The Inaccessible Island Rail, Atlantisia rogersi, is a small bird of the rail family, Rallidae. It is found only on Inaccessible Island in the Tristan Archipelago, and is notable for being the smallest extant flightless bird in the world. Unlike many other islands, Inaccessible Island has remained free from introduced predators, allowing this species to flourish while many other flightless birds, including the even smaller Stephens Island Wren, have perished. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

Two larger species from the same genus are extinct: The Ascension Flightless Rail (Atlantisia elpenor) disappeared around 1700, but was briefly mentioned and described by traveller and hobby naturalist Peter Mundy in 1656. Atlantisia podarces, the St. Helena Flightless Rail, disappeared around 1600 and has never been encountered by scientists. Both species became extinct due to predation by introduced species, mainly cats and rats. In biology, a genus (plural genera) is a grouping in the classification of living organisms having one or more related and morphologically similar species. ...
