The Australian Bustard, Ardeotis australis, is a large ground bird of grassland, woodland and open agricultural country across northern Australia and southern New Guinea. It is also commonly referred to in Central Australia as the Bush Turkey, particularly by Aboriginal people.
The Brolga (Grus rubicunda) is a bird in the crane family. When first described in 1810, the Brolga was misclassified as Ardea, the genus that includes the herons and egrets. It is in fact a member of the Gruiformes – the order that includes the crakes, rails, and cranes, and a member of the genus Grus. The bird was later given the name "Australian Crane" in 1865 by well-known ornithological artist John Gould.
The Lord Howe Island Rail, Gallirallus sylvestris, also known as the Lord Howe Rail or popularly in Australia as the Lord Howe Island Woodhen, is a flightless bird of the rail family (Rallidae). It is endemic to Lord Howe Island off the Australian coast. It is a small olive brown bird, with a short tail and a downcurved bill. The Lord Howe Island Rail lives in sub-tropicalforests, feeding on earthworms, crustaceans, fruit, and taking the eggs of shearwaters and petrels.
The Purple Swamphen (Porphyrio porphyrio), also known as the African Purple Swamphen or Purple Moorhen or Purple Gallinule, is a large bird in the family Rallidae. From its name in French, talève sultane, it is also sometimes known as the Sultana Bird. It should not be confused with the American Purple Gallinule, Porphyrio martinica. The Māori name for the subspecies P. p. melanotus, Pūkeko, is the common name in New Zealand.
The Sarus Crane, Grus antigone is an all-year resident breeding bird in northern Pakistan and India (especially Central India and the Gangetic plains), Nepal, Southeast Asia and Queensland, Australia. It is a very large crane, averaging 156 cm (5 ft) in length, which is found in freshwater marshes and plains.
The Tasmanian Native-hen (Gallinula mortierii) is a flightless water hen, one of twelve species of birds endemic to Tasmania. Many flightless birds have a sad history of extinction at the hands of man. The Tasmanian Native-hen has actually benefited from the introduction of european style agricultural practices in Tasmania (Ridpath: 1964).
The Lord Howe Swamphen, or White Gallinule, (Porphyrio albus) was a large bird in the family Rallidae. It was similar to the Purple Swamphen, but with shorter and more robust legs and toes. Its plumage was white, sometimes with a few blue mottles, and it was probably flightless, like its other close relative the Takahe. Similar, entirely blue birds were also described, but it is not clear if they belong to this species or are simply Purple Swamphens (which can also be found on the island). The feathers on the two extant skins are white.
