chatham shag

Large, 63cm metallic black-green and white sea bird. Feeds at sea by diving for small fish, nests in groups on bare rock on headlands and islands. Halved in number since 1997, about 1000 remain on the Chatham Islands, New Zealand. Breeding groups of adults suffer from being panicked by farm animals and people. Dogs, cats and pigs introduced by people eat their eggs and nestlings.
