Distribution, inland areas of Australia generally, extending to the coast in the west and northwest and occasionally in eastern Australia and also in New Guinea.
In appearance this species suggests a small wedgetailed eagle. Usually in pairs, frequenting chiefly inland districts; it shows a preference for country intersected by creeks. Usually seen high in slow wheeling flight; performs spectacular courtship display flights. In some districts it survives almost entirely on rabbits; it also feeds on other small mammals and reptiles. The call is a shrill rapid double whistle.
Like many hawks, the species is very variable in plumage with two recognisable colour-phases, light and (more rarely) dark, as well as intermediates. Breeding season is August to November. The nest is large, compact, made of sticks and twigs lined with green leaves; usually high in a leafy tree; occasionally use abandoned nests of other species. Eggs: 1 sometimes 2; bluish white with reddish-brown spots.
