Circus approximans
The Swamp Harrier is a large, slim-bodied bird of prey that is easily recognised by its prominent white rump patch, especially visible when it glides low over wetlands and open country. This adaptable raptor is a familiar sight in Australia’s marshes, reed beds, and grasslands, where it hunts with slow, low flight and wings held in a shallow V-shape.

Swamp Harriers are opportunistic hunters, feeding on birds, small mammals (including rabbits), reptiles, frogs, insects, and carrion. They breed from September to December, with nests built on the ground or in dense reeds, usually as a single pair. The female incubates and broods the young, while the male provides food, sometimes transferring it in mid-air. Swamp Harriers are partly migratory-some populations move north in winter, while others remain resident
Swamp Harriers are widespread across Australia (except arid regions), New Zealand, and several Pacific islands. They favour wetlands, including swamps, reed beds, and marshes, but also hunt over grasslands, farmland, and coastal areas. Look for them gliding just above vegetation, especially at dawn and dusk when they are most active. They typically nest in dense reeds or tall grasses, often above water.
