Wedge-tailed Eagle Identification Guide

Key Field Marks

• Size and shape: Australia's largest bird of prey, with a wingspan up to about 2.3 m. In flight, shows long, broad, "fingered" wingtips and a long, unmistakably diamond/wedge-shaped tail — the defining feature of the species.
• Plumage: Adults are dark blackish-brown overall, appearing almost black at a distance, with paler golden-brown feathering on the nape and hackles.
• Legs: Fully feathered down to the toes, typical of true (Aquila) eagles.
• Juveniles/immatures: Much paler rufous-brown, gradually darkening with each molt over roughly a decade until reaching full adult darkness.
• Flight: Soars with wings held in a shallow V (dihedral), often at great height, riding thermals for long periods.

Separating It From Similar Species

• Whistling Kite / Black Kite: Both are considerably smaller with rounded or shallowly forked tails, not the long wedge shape, and lighter, more buoyant flight.
• Little Eagle: Much smaller, with a shorter, squarer tail and different underwing pattern.
• Black-breasted Buzzard: Smaller, with a rounder tail and different wing markings (pale "windows" near the wingtips). Overall, sheer size combined with the long wedge-shaped tail makes adult Wedge-tailed Eagles hard to mistake once seen well.

Habitat, Range & Season

Found throughout mainland Australia and Tasmania across almost every habitat type — open woodland, arid interior country, forest edges, farmland, and even semi-desert. Frequently seen soaring at height or perched on roadside poles and trees, and is a regular scavenger at roadkill along highways. Largely sedentary, with some local and altitudinal movements.

Voice

Relatively quiet away from the nest. Gives thin, high-pitched whistling or yelping calls, most often around the nest site or in territorial interactions.
