- Wingspan
- 200 cm
- Family
- Accipitridae
Identification
A great coastal eagle: white head, breast and tail against a grey mantle, a massive bill, and a short wedge of a tail in flight. Adults are cleanly pied; immatures are mottled brown for several years and are often mistaken for something lesser. Nothing else over the bay has that bulk and that calm.
Distinctive marks
- White head, underparts and tail (adult)
- Grey back and wings
- Huge yellow bill
- Short wedge-shaped tail in flight
- Soars on broad, upswept wings
Behaviour & ecology
They hunt along the shore and over open water, taking fish, seabirds, and the occasional rabbit. A pair holds a territory for years and builds a vast stick nest in a tall tree or on a cliff. Most of what you will see is a bird going somewhere with the patience of weather.
Voice
A goose-like honking, surprisingly un-eagle, often given in a soaring duet.
On the Peninsula
The bays and ocean coast of the Peninsula, Western Port, and large inland waters. A bird of the horizon more than the nature strip.
Season
Year-round. Winter soaring over the bay is the surest hour.
Diet
Fish, waterbirds, carrion, and the odd mammal taken from open ground.
Conservation
Listed as Vulnerable or Endangered in parts of south-east Australia. Disturbance at nests and loss of tall roost trees are the local pressures.
Lore & resonance
A sea-eagle does not visit a beach. It claims the air above it. When one crosses the mouth of an estuary, the smaller birds rearrange themselves, and so should you.
If you would attract them
You do not attract an eagle. You leave the tall roost trees standing, give nests a wide berth in winter and spring, and look up when the gulls go quiet.
