An adult wedge-tailed eagle at Lake Burrumbeet in flight, notably dark and blackish colour. A young wedge-tailed eagle perched in Birdsville Track with an unusual amount of pale colour showing due likely to moult. The species was first described in 1801 by the English ornithologist John Latham, under the binomial name Vultur audax. [13]
It is estimated that the wedge-tailed eagle has a visual acuity twice that of a typical human. [5] [6] [7] ... Hunting techniques differ among the species and genera ...
Using this method, accipitrids such as the golden eagle (Aquila chrysaetos), wedge-tailed eagle (Aquila audax), martial eagle (Polemaetus bellicosus) and crowned eagle (Stephanoaetus coronatus) have successfully hunted ungulates, such as deer and antelope, and other large animals (kangaroos and emus in the wedge-tailed) weighing more than 30 kg ...

The visual acuity of some large raptors such as eagles and Old World vultures are the highest known among vertebrates; the wedge-tailed eagle has twice the visual acuity of a typical human and six times that of the common ostrich, the vertebrate with the largest eyes. [41]
The wedge-tailed eagle is not necessarily a predator of the little eagle but the two species share common habitat and prey and the large size and dominant nature of the wedge-tailed eagle could mean that the little eagle would be forced out of hunting and breeding grounds or even killed and eaten.
Other booted eagles in the golden eagle's range are unlikely to be confused due to differences in size and form. The only species in the genus Aquila that exceeds the golden eagle in average wingspan and length is the wedge-tailed eagle of Australasia; however, the wedge-tailed eagle is a slightly less heavy bird. [21]
The average estimated weight of prey taken by most other Aquila species is generally much lower but the wedge-tailed eagle seemingly takes prey of a similar weight (both in average and range of prey weights) while the Verreaux's eagle average prey weight is higher, probably over 2 kg (4.4 lb).
