The once abundant Tristan Moorhen had become rare by 1873, and by the end of 19th century it was extinct as a result of hunting, predation by introduced species and habitat destruction by fire. A handful of taxidermical specimens of the Tristan Moorhen have been preserved, including one at Harvard University.
The Tristan Gallinule is classified as Extinct (EX), there is no reasonable doubt that the last individual has died.
