![]() In parts of Australia where there are no large trees available, the eagles will create nests in shrubs, on telegraph poles, on cliff faces and even on the ground. Nests are usually built in the tallest tree in the vicinity, commanding an impressive view of their territory. The nests are so large that smaller birds, like finches, can nest in the underside, benefiting from the protection from predators offered by the eagles! Breeding pairs are territorial, and will defend their hunting ground and their large, impressive nests.īuilt of sticks and lined with leaves, their nests can measure 2m across, 3m deep and weigh more than 400kg! Wedge-tailed Eagles are monogamous: they mate for life. The Tasmanian subspecies (Aquila audax fleayi) is listed as Endangered under the Environment Protection and Biodiversity Conservation Act 1999. 1 While it’s listed as of Least Concern on the the IUCN Red List of threatened species, it’s fully protected in all Australian states and territories. The species is considered the most common of the world's large eagles. It’s seldom seen in rainforests or coastal heaths. It prefers wooded areas and open forests, but can be found in coastal and alpine regions. The Wedge-tailed Eagle has an extremely large range: it’s found throughout mainland Australia, Tasmania and southern Papua New Guinea. The name Aquila audax, means bold eagle in Latin. For the Kaurna people of the Adelaide Plains, the eagle’s claw takes the form of a constellation known as Wilto (the Southern Cross). Wedge-tailed Eagles feature in many dreaming stories for Aboriginal Australians: for example, the eagle Bunjil is an important creator being for the Kulin people of central Victoria. Once on the wing, they soar with ease, circling at great heights to altitudes of 2,000m!įrom below you can see its flight feathers stretched like fingers and the wedge-shaped tail that gives the species its common name. Have you seen a Wedge-tailed Eagle take off from the ground? You might remember the bird’s heavy flight, its slow, powerful wing beats. The bird’s long powerful legs are feathered to the base of the toe. ![]() Young birds have brown feathers that become progressively darker as the bird ages mature adults are dark brown to black with white and bronze feathers on their necks and wings. ![]() It can weigh 4kg, measure 1m from head to tail-tip and has a wingspan of up to 2.3m (females are larger than males). Like other birds of prey, it has a hooked bill and large talons. Scientists are certain that the largest bird in history got its huge bulk up and flying, but how did it do so, exactly? The aforementioned condor is the world's largest flying bird, but the heaviest - Africa's kori bustard - requires a running start to take to the skies, and it weighs less than a third of Argentavis.The Wedge-tailed Eagle is one of 24 diurnal (day-active) raptor species in Australia. The Andean condor is the current biggest bird in the sky, and it still weighs six times less as Argentavis and boasts only half the wingspan of its ancient ancestor. This prehistoric avian giant belonged to an extinct family of predatory birds that taxonomists justifiably dubbed teratorns, or "monster birds." Argentavis far outweighed even the largest of its closest modern descendants, like storks, American vultures, and condors. It averaged a hefty 70 kilograms (that's over 150 pounds!), and its wingspan measured 7 meters, nearly 23 feet from tip to tip. Big enough for National Geographic to compare the formidable raptor to a Cessna 152 two-seater airplane. ![]()
