Wedge-tailed eagles are also known to at times prey on another animal introduced for human hunting purposes, the red fox (Vulpes vulpes), which can form up to about 4% of an eagle's breeding diet and 5% of the biomass, weighing up to 9 kg (20 lb). In Canberra, about 59% of the foxes found in the diet were adults.

Aquila is the genus of true eagles. The genus name is Latin for "eagle", possibly derived from aquilus , "dark in colour". [ 1 ] It is often united with the sea eagles , buteos , and other more heavyset Accipitridae , but more recently they appear to be less distinct from the slenderer accipitrine hawks than previously believed.
[5] [6] In wingspan, extant Aquilinae range from the pygmy eagle, with a median of 1.18 m (3 ft 10 in), to the wedge-tailed eagle (Aquila audax) and martial eagles, which average about 2.15 m (7 ft 1 in) and 2.12 m (6 ft 11 in) in wingspan, respectively. Total length can vary from 38 to 106 cm (15 to 42 in), in the pygmy and wedge-tailed eagles ...
The white-tailed eagle does appear to outsize the average wingspan of the wedge-tailed eagle (Aquila audax), which is sometimes also titled the largest winged extant eagle due to an exceptionally large individual shot in 1931, [33] although the Steller's sea eagle may rival it in that respect.
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 ...
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.
