The Notornis is an endangered flightless bird species native to New Zealand. It is also known by several other names, including the Takahe, Porphyrio hochstetteri, or Dinornis hochstetteri. The word "Notornis" originates from the Greek words "notos" and "ornis," which means "southern bird." Takahe is the Maori name for this bird, which means "stranger" or "rare." The species was previously thought to be extinct, but a small population was rediscovered in the 1940s. Today, conservation efforts are underway to protect the remaining individuals. Synonyms for Notornis include flightless rail, swamp-hen, and large purple gallinule.
