Most species are found in Africa but others occur in southern Europe, Madagascar, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All are colourful and have long downturned bills and pointed wings, which give them a swallow-like appearance when seen from afar. Order: CoraciiformesFamily: Coraciidae  2 species recorded [1 extant native, 1 vagrant] Rollers resemble crows in size and build, but are more closely related to the kingfishers and bee-eaters. They share the colourful appearance of those groups with blues and browns predominating. The two inner front toes are connected, but the outer toe is not. Order: FalconiformesFamily: Falconidae  7 species recorded [6 extant native, 1 vagrant] Falconidae is a family of diurnal birds of prey. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons. Order: PsittaciformesFamily: Nestoridae  1 species recorded [1 extinct native] The family diverged from the other parrots around 82 million years ago when New Zealand broke off from Gondwana, while the ancestors of the genera "Nestor" and "Strigops" diverged from each other between 60 and 80 million years ago. Order: PsittaciformesFamily: Cacatuidae  14 species recorded [14 extant native] The cockatoos share many features with other parrots including the characteristic curved beak shape and a zygodactyl foot, with two forward toes and two backwards toes. They differ, however in a number of characteristics, including the often spectacular movable headcrest. Order: PsittaciformesFamily: Psittaculidae  44 species recorded [42 extant native, 1 extirpated native, 1 extinct native] Characteristic features of parrots include a strong curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. In size they range from to in length. Old World parrots are found from Africa east across south and southeast Asia and Oceania to Australia and New Zealand. Order: PasseriformesFamily: Pittidae  6 species recorded [3 extant native, 3 vagrant] Pittas are medium-sized by passerine standards and are stocky, with fairly long, strong legs, short tails, and stout bills.
