Pterodroma magentae (Magenta Petrel)

Wikipedia Abstract

The Magenta petrel or Chatham Island taiko (Pterodroma magentae) is a small seabird in the gadfly petrel genus, Pterodroma. The first specimen of the Magenta petrel was collected from His Italian Majesty's ship Magenta on July 22, 1867 in the South Pacific ocean, midway between New Zealand and South America. The link between it and the presumed-extinct Chatham Island taiko was only confirmed when the first taiko was caught on Chatham Island, New Zealand by David Crockett on January 1, 1978. Formerly widespread on Chatham Island, the taiko is now confined to the forested Tuku valley system on the south-west of the island.
