The largest bird of prey in Australia, the Wedge-tailed Eagle is a huge, powerful eagle with long wings (2.3m) and a distinctive diamond-shaped tail. It has a relatively small, flat head with a massive, formidable beak. Its legs are covered in baggy feathering all the way to the feet. Adults are mostly dark blackish-brown with brown eyes and the cere (top of beak) and feet are creamy white. The female is slightly larger and heavier than the male. The Wedge-tailed Eagle is widespread across Australia, including Tasmania and also occurs in parts of southern Papua New Guinea. This large eagle is found in a wide variety of habitats, from forest and woodland to savanna and treeless plains. They hunt a variety of mammals, as well as some reptiles and birds as well as carrion. Where they are common, rabbits make up most of the Wedge-tailed Eagle’s diet, but they will also take wallabies, kangaroos, hares, possums, cats, dogs, foxes, young goats and lambs. This powerful eagle is capable of taking prey several times its own weight and they sometimes hunt co-operatively in pairs or even in small groups.

The Wedge-tailed Eagle is Australia's largest living bird of prey and one of the largest eagles in the world. The Wedge-tailed Eagle has long wings (wingspan 2.3 m), a characteristic long, wedge-shaped tail, and legs that are feathered all the way to the base of the toes. The bill is pale pink to cream, the eye brown to dark brown, and the feet off-white. Young Wedge-tailed Eagles are mid brown in colour with reddish-brown heads and wings. They become progressively blacker for at least the first ten years of their lives; adults are mostly dark blackish-brown. The only difference in plumage between the sexes is that a female adult is generally slightly paler than her mate. Females (4.2 kg - 5.3 kg) are also larger and heavier than males (3.2 kg up to 4.0 kg). Wedge-tailed Eagles are Australia's largest raptors (birds of prey). Australia's second largest eagle (and second-largest bird of prey), the White-bellied Sea-Eagle, Haliaeetus leucogaster , has shorter, more rounded wings and no feathers on its lower legs.

The Wedge-tailed Eagle is Australia’s largest living bird of prey and one of the largest eagles in the world. Wedge-tailed Eagles eat both live prey and carrion. Their diet reflects the available prey, but the most important live items are rabbits and hares. Rabbits usually comprise about 30-70% of the diet, but may comprise up to 92%. The introduction of the calicivirus has resulted in the decline of rabbits in many parts of Australia. It is not yet known how this will affect the Wedge-tailed Eagle. Other food items include lizards, birds (weighing over 100 g) and mammals (usually weighing over 500 g). Wedge-tailed Eagles will kill lambs, but these make up only a small percentage of their total prey. Wedge-tailed Eagle - BirdLife Australia

The wedge-tailed eagle (Aquila audax) is the largest bird of prey in the continent of Australia. It is also found in southern New Guinea to the north and is distributed as far south as the state of Tasmania. Adults of the species have long, broad wings, fully feathered legs, an unmistakable, wedge-shaped tail, an elongated upper mandible, a strong beak, and powerful feet. The wedge-tailed eagle is one of 12 species of large, predominantly dark-coloured booted eagles in the genus Aquila found worldwide. Genetic research clearly has indicated that the wedge-tailed eagle is fairly closely related to other, generally large members of the Aquila genus. A large, brown-to-black bird of prey, it ha…

The Diet of the Wedge-Tailed Eagle, Aquila Audax, in Western Australia.. The diet during nesting of the wedge-tailed eagle Aquila audax was examined in several regions of Western Australia. On the arid Nullarbor Plain, rabbits were by far the major food item despite the presence of a number of other prey species. In the south-west of the State, which has a Mediterranean climate, birds (especially ducks, parrots and corvids), rabbits and sheep were the most important foods in a very diverse diet. On the arid western coast near Carnarvon, kangaroos and sheep predominated as food but a number of foxes and cats were also taken. In northern Western Australia, macropods appeared to be the main fo…

Food habits of nesting Wedge-Tailed Eagles, Aquila audax, in South-Eastern Australia. Food habits of nesting wedge-tailed eagles were studied by gathering and identifying materials brought to the nests to feed the young. Near Canberra, A.C.T., 31 inactive nests yielded 1923 identifiable food fragments and 157 pellets. In north-western New South Wales 28 nests yielded 1274 identified fragments and 52 pellets. During the nesting season 18 active nests were visited at least weekly and 260 fresh prey animals were recorded. Rabbits constituted the primary prey of eagles. Near Canberra the hare was the next most important species, followed by birds, sheep and lambs, small mammals, and lizards. In…

The white-bellied sea eagle (Icthyophaga leucogaster), also known as the white-breasted sea eagle, is a large diurnal bird of prey in the family Accipitridae. Originally described by Johann Friedrich Gmelin in 1788, it is closely related to Sanford's sea eagle of the Solomon Islands, and the two are considered a superspecies. A distinctive bird, the adult white-bellied sea eagle has a white head, breast, under-wing coverts and tail. The upper parts are grey and the black under-wing flight feathers contrast with the white coverts. The tail is short and wedge-shaped as in all Haliaeetinae species. Like many raptors, the female is larger than the male, and can measure up to 90 cm (35 in) long…
