The Australasian Gannet (Morus serrator), also known as Takapu (Maori), is mostly white, with black flight feathers at the wingtips and lining the trailing edge of the wing. The central tail feathers are also black. The head is yellow, with a pale blue-grey bill edged in black, and blue-rimmed eyes. They normally nest in large colonies on coastal islands, an exception to this being the colonies on New Zealands mainland at Cape Kidnappers (5000+ pairs), Muriwai and Farewell Spit. Gannet pairs may remain together over several seasons. They perform elaborate greeting rituals at the nest, stretching their bills and necks skywards and gently tapping bills together. The adults mainly stay close to colonies, whilst the younger birds disperse. These birds are plunge divers and spectacular fishers, plunging into the ocean at high speed. They mainly eat squid and forage fish which school near the surface.
