Magenta petrel

The magenta petrel (Pterodroma magentae), or Chatham Island tāiko, is a small seabird in the gadfly petrel genus, Pterodroma. Found exclusively on Chatham Island, New Zealand, it is one of the rarest birds in the world, believed to be extinct for over 100 years before its rediscovery in the 1970s.

This medium-sized petrel has a brownish-grey head, neck, and upper breast, with white underparts. The undersides of the wings are brown. It has a black bill and pink legs. Adults weigh 400–580 g.

The bird nests in 1–3 m long burrows under dense forest. They form long-term monogamous pair bonds, raising one egg at a time, and both partners incubate the egg and feed the chick. The breeding season is between September and May, during which time the birds forage over the open ocean.
