Below a rough estimate of the altitude at which a Wedge-tailed Eagle was observed: Assuming that the airplane was flying at 10000 m altitude (33000 ft), based on its length of 70.6 m and the eagle's length of ca. 1 m, one can estimate from the relative apparent sizes that the eagle was seen at an altitude of roughly 800 m. The uncertainty in the length of the bird and the altitude of the airplane is about ±10%, making the total uncertainty of the bird's altitude about ±20%.

These two photos give an estimate of how high a "Wedgy" can fly; Wedge-tailed Eagle at 15x magnification (left) and, on the same scale, a Boeing 747-400 at cruising altitude (right)

Breeding information

Breeding season: Jun - Aug Eggs: 1 - 3 Incubation period: 45 days Fledging age: ca. 70 days

The breeding season depends significantly on geographical latitude. In the tropical north Wedge-tailed Eagles breed Jan - Feb. Although there can be up to 3 eggs, normally only one, sometimes two chicks survive.

Twitcher's tip

Note that, by the time they fledge (i.e., leave their nest), the young of all species of raptors - apart from the tail and wing feathers (which are still growing) - are already full adult-size.


"bungobittah", "malunna" = Nest [Aboriginal]

Type: Basket Material: Sticks, lined with fresh leaves Height above ground: 5 - 20 m

The nest will start relatively small and grow in size with time, up to a total weight of about one tonne. Therefore, Wedge-tailed Eagles choose the strongest forks available in the tallest suitable tree they can find.

Additional information

A. Morris reports that some bird species, most notably Diamond Firetails, Zebra Finches and Red-browed Finches, like to take advantage of the protection offered by nesting under a Wedge-tailed Eagle nest. There is now a separate page about various bird species nesting under the umbrella of a stronger, protective species.

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "ngampu", "nooluk", "pateena" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 75 x 58 mm Colour: Light-brown, heavily speckled with darker brown speckles Shape: Tapered oval


Social behaviour: Territorial Mobility: Sedentary Elementary unit: Pair

Additional information

For a Wedge-tailed Eagle it is usually not a good idea to fly low past an Australian Magpie nest. There is a short page describing such an unpleasant experience.

Food, Diet

Adults: Mammals, carrion Dependents: As adults Water intake: None

All raptors are carnivores. Wedge-tailed Eagles prey on animals as large as (young) kangaroos. They also scavenge on carrion, e.g. roadkill. The photo below indicates that immature birds start with smaller prey. They have been seen by us competing with adult Whistling Kites.

During the first few weeks, raptors feed their chicks with pieces of meat. Later on in their development, the chicks learn to tear apart their parents' prey.

Australia does not have any vultures. The Wedge-tailed Eagle fills that void in the ecosystem. Together with ants and Whistling Kites they dispose of dead bodies.

Early morning clean-up: Two of a total of five Wedge-tailed Eagles seen near roadkill (in this case a young kangaroo); in the absence of vultures on the Australian continent, Wedge-tailed Eagles fill that ecological niche
