Australian bustard
The Australian bustard (Ardeotis australis) is a large ground-dwelling bird that is common in grassland, woodland and open agricultural country across northern Australia and southern New Guinea. It stands at about one metre (3 ft 3 in) high, and its wingspan is around twice that length. The species is nomadic, flying to areas when food becomes plentiful, and capable of travelling long distances. They were once widespread and common to the open plains of Australia, but became rare in regions that have been used for farming. The bustard is omnivorous, mostly consuming the fruit or seed of plants, but also eating invertebrates such as crickets, grasshoppers, smaller mammals, birds and reptiles.
The species is also commonly referred to as the plains turkey, and in Central Australia as the bush turkey, particularly by Aboriginal people, who hunt it, although the latter name may also be used for the Australian brushturkey, as well as the orange-footed scrubfowl.
The species was first described by John Edward Gray in 1829, who assigned it the name Otis australis. Gray's specimen was obtained in New South Wales and was held in the General T. Davies collection. The whereabouts of that type is now unknown, after being sold to a private buyer. John Gould also provided a description in 1841, and named the bird Otis australasianus, using a skin obtained in Western Australia. That specimen was later nominated as the syntype and is held at the Academy of Natural Sciences of Philadelphia.
Placement within the family Otididae has been variously assigned. Gray recognised the species in the genus Otis in the first description, Gregory Mathews later proposed the names Choriotis and Austrotis, along with subspecific descriptions, and it was placed as a species of Eupodotis in the mid-twentieth century.
Common names for Ardeotis australis include bustard, Australian bustard, plains turkey, wild turkey and native turkey. The Arrernte name for the bird is kere artewe, and the Luritja name is kipara. The Larrakia name is danimila. The species is also presumed to be important to the Noongar peoples, whose names for the bird included the word bebilya, recorded by John Gilbert and published in Birds of Australia (Gould, 1848).
The only Australian species of Ardeotis, a genus occurring in the African, Indian and Australasian regions, this bustard is a large terrestrial bird that resembles an American turkey in its form and behaviour. It is readily distinguished by its large size, long legs and habits while slowly striding across open plains. The general coloration of A. australis is black at the crown and nape, the long neck is pale grey at the front, and brown plumage cover the wings and upper body. The sexes are similar in appearance, females are smaller in stature, wingspan and weight than the males. The abdomen is white and separated from the light grey of the neck by a black band of feathers. The wing coverts are patchily coloured with black and white patterning, which is visible while at rest or especially in flight. The iris is white, and their beak is variously whitish to brown in colour. The legs are long and yellow to cream coloured.
Males are up to 1.2 m (47 in) tall with a 2.3 m (7.5 ft) wingspan. The average weight for males is 6.3 kg (14 lb), with a range of 4.3 to 12.76 kg (9.5 to 28.1 lb). The female is quite a bit smaller at 80 cm (31 in) tall, with a 1.8 m (5.9 ft) wingspan and an average body mass of 3.2 kg (7.1 lb) in a range of 2.4 to 6.35 kg (5.3 to 14.0 lb) but is similarly coloured.
The largest male recorded was 14.5 kg (32 lb), a specimen obtained in Victoria. Reports of large birds, presumably males, were given by Tom Carter in the west (16 lb), a recorded range of 16–18 lb by E. F. Boehm in South Australia was exceeded in some specimens (28 lb). The smaller specimens in records are of an unwell adult weighing 9 lb, shot by Carter at Broomehill, and a healthy but small specimen of 7½ lb captured and weighed by Dominic Serventy and Hubert Whittell at Bridgetown in 1949. Although it is the largest extant flying land bird in Australia, this long-legged bird is the smallest species in the genus Ardeotis.
