Porphyrio mantelli
(Owen, 1848)

The North Island Takahē or mōho, Porphyrio mantelli, is an extinct rail that was found in the North Island of New Zealand. This flightless species is known from subfossils from a number of archeological sites and from one possible 1894 record (Phillipps, 1959).

The decline of the species has generally been attributed to the increasing incursion of forest into the alpine grasslands through the Holocene, although hunting by the Māori probably also played a role.

Traditionally the North Island Takahē was considered conspecific with the threatened South Island Takahe P. hochstetteri. Trewick (1996) presented evidence that the two taxa were indepently derived from flying ancestors, so proved to be separate species.
