(species Notornis mantelli), rare flightless bird of New Zealand that was thought to have become extinct in the late 1800s but that was rediscovered in 1948 in several remote valleys on South Island. Related to the gallinules (family Rallidae), it is a colourful species with brilliant blue and coppery-green plumage and a large red bill, surmounted by a red frontal shield that protrudes from the forehead. The takahe feeds by stripping seeds from grasses. The nest is placed on the ground, and two eggs, cream-coloured with brown blotches, are laid. The young are black and downy
