The Wedge-tailed Eagle is Australia's largest bird of prey. The canonical female weighs about 4.2 kg and spans about 2.2 m. It has some of the sharpest measured vision of any animal and hunts rabbits, hares and wallabies, while pairs and groups can bring down adult kangaroos. Alone, its light build and modest talons keep it below the golden eagle in raw killing power.
Detailed ratings
Research-backed ratings on one 0–100 scale for all 341 animals (updated 2026-09-28). How ratings work
Special abilities
Pairs and groups hunt together: one eagle distracts or drives the prey while another strikes, and in large group hunts fresh pairs replace tired chasers. Together they can kill adult kangaroos that no single eagle could handle.
Behavioural tests measured acuity of 132–143 cycles per degree, matching the limit of its deep fovea. It can spot prey and threats from far beyond the range at which they can see the eagle.
Unique traits
A Tasmanian female measured 284 cm, the largest verified wingspan for any eagle, and the long wedge-shaped tail is unique among large Australian raptors.
It is the only bird with a reputation for frequently attacking hang gliders and paragliders, and it also attacks drones.
How it fights
Weapons
- The feet and talons are the killing tools. The hallux claw (about 4.5–4.6 cm in mainland females) is somewhat smaller than a golden eagle's, but it is very sharp, and the whole foot is feathered to the toes. The bill tears carcasses and kills. Rabbits and hares are the most important live prey, and the species also takes macropods (kangaroos and wallabies), lizards such as bearded dragons, birds over about 100 g and mammals usually over 500 g. It also eats a lot of carrion, including roadkill. It kills lambs occasionally, but lambs are a small part of the diet.
- Its most striking offensive behavior is cooperative. Australian Museum and BirdLife Australia both state that a group of eagles working together can kill animals as large as adult kangaroos. In one Central Australian study, about a third of 89 observed hunts were cooperative. One record describes 15 eagles hunting kangaroos, with two chasing at a time and fresh pairs taking over from the circling group.
Struggles vs
- About 4.2 kg in absolute mass.
- Smaller talons than golden or Verreaux's eagles.
- No armor; light skeleton.
- Gorged birds on the ground can struggle to take off.
- Heavy reliance on carrion exposes it to lead poisoning and roadkill collisions.

Fun facts
- A Tasmanian female had a verified wingspan of 284 cm, the largest measured for any eagle.
- Its visual acuity was measured at 132–143 cycles per degree, close to the limit set by the optics of its eye.
- Groups of wedge-tailed eagles can kill adult kangaroos.
- Old nests can weigh around 400 kg.
- Its scientific name audax means "bold".
- It is famous for attacking hang gliders and paragliders, and eagles once knocked nine of a mining company's drones out of the sky.

L Wedge-tailed Eagle battle analysis
The wedge-tailed eagle is built for wide country. Its long wings and long, wedge-shaped tail let it ride thermals to 2 km or more over the Australian interior. From there, eyes measured at 132–143 cycles per degree, close to the physical limit for a vertebrate eye, pick out rabbits, hares, lizards and carcasses far below.
Much of its daily food is ordinary: rabbits, roadkill and whatever is plentiful. What makes it stand out is cooperation. Pairs hunt in tandem, one bird drawing attention while the other strikes. Groups have been seen running down kangaroos in relays, with fresh eagles dropping in to replace tired chasers. In the Strzelecki Desert, eagles on the side of the dingo fence where kangaroos are abundant ate far more of them.
Alone in an absolute matchup, it is a 4.2 kg bird with talons a little smaller than a golden eagle's and no armor. It wins with vision, surprise and, when it has help, numbers. Against a heavy grappler that survives the first strike, one eagle has little left to use.
Habitat & range
The wedge-tailed eagle is found throughout mainland Australia and Tasmania and on many offshore islands. It uses more habitat types than perhaps any other Aquila eagle, from deserts and arid shrubland to farmland, open woodland and mountain forest with an open understory. It is common across the arid interior wherever prey and nest trees or cliffs are available.
Diet & hunting
It is a generalist predator and a major scavenger. Rabbits and hares are the most important live prey; macropods, lizards, birds and other mammals are also taken, and carrion, including roadkill kangaroos, makes up a large part of the diet. In the Strzelecki Desert, where dingoes are rare, eagles ate more kangaroos and bearded dragons and a wider range of species than on the other side of the dingo fence. By eating rabbits, it helps limit an invasive pest.
Social life
Breeding adults live as long-term territorial pairs. Around each defended nest territory is a larger home range that overlaps with neighbors and non-breeding birds. Pairs, and sometimes larger groups, hunt together.
Conservation
The species is listed as Least Concern globally. Persecution was heavy in the past because of supposed lamb killing, but numbers recovered strongly, helped by rabbits and roadkill. The Tasmanian subspecies is listed federally as Endangered. Current threats include lead poisoning from ammunition in carcasses: lead was detected in 84% of 62 mainland eagle bones, at severe levels in 4.8%. Rodenticide exposure (residues in 74% of 50 Tasmanian carcasses) and collisions with vehicles while feeding on roadkill are also threats.
