Takahē
The takahē, ''Notornis'', or South Island takahē (''Porphyrio hochstetteri'') is a flightless bird indigenous to New Zealand and belonging to the rail family. It was thought to be extinct after the last four known specimens were taken in 1898. However, after a carefully planned search effort the bird was rediscovered by Geoffrey Orbell near Lake Te Anau in the Murchison Mountains, South Island, on 20 November 1948. The specific scientific name commemorates the Austrian geologist Ferdinand von Hochstetter. ==Taxonomy and systematics== A related species, the North Island takahē (''P. mantelli'') or ''mōho'' is extinct and only known from skeletal remains. Both forms were long assumed to be subspecies of ''mantelli'', and were usually placed in the genus ''Notornis''. However, it has been determined that the differences between ''Porphyrio'' and ''Notornis'' were insufficient for separating the latter, whereas the differences between the North and South Island forms justified the splitting into two species, as each evolved independently towards flightlessness.〔Trewick, S.A. & Worthy, T.H.
