Black-breasted Buzzard

Identification

The black-breasted buzzard is one of Australia's largest birds of prey, measuring 51 to 61 cm in height with an impressive wingspan of 141 to 156 cm. Its most distinctive feature is the striking contrast between mainly black underparts and thick white panels near the wing tips, visible when the bird is in flight. From above, the black plumage is broken by rich mottled red across the back and shoulders. Adults appear sexually monomorphic, though females are slightly larger, weighing around 1,330 g compared to males at 1,196 g. Immature and juvenile birds display pale brown colouring with increasing dark streaks as they age. The species' conspicuously long wings relative to its stout body and short square tail make it distinctive in flight.

Range & Habitat

The black-breasted buzzard is endemic to mainland Australia, widely but sparsely distributed across northern and inland regions receiving less than 500 mm annual rainfall. Its range stretches from north-eastern South Australia, north-western New South Wales, northern Queensland, the Northern Territory, and the north-western reaches of Western Australia. The species is notably absent from Victoria, the Australian Capital Territory, and Tasmania, where wetter temperate climates prevail.

Found in wooded and open habitats, the buzzard shows a strong preference for riparian forests and tall-open woodlands surrounded by mid-dense shrublands. River Red Gum woodlands are particularly favoured across central Australia, representing the species' most commonly observed habitat type.

Behaviour & Diet

The black-breasted buzzard is a versatile and opportunistic hunter employing diverse foraging techniques. It hunts reptiles, small mammals including young rabbits and rodents, large insects, and birds up to the size of pigeons and ducks. The species also raids bird nests for eggs and nestlings, even targeting other raptor species. Carrion of large mammals found along roads, tracks, and creek lines frequently supplements its diet. The buzzard searches for food by soaring in transects over low vegetation, engaging in cooperative hunting with other individuals, or observing from high unconcealed perches, attacking prey by dropping, pouncing, diving, or gliding.

The species is renowned for its remarkable skill in using stones to crack the eggs of large ground-nesting birds such as emus, magpie geese, brolgas, and Australian bustards. Stones are either dropped onto or thrown at eggs to break them open, or the buzzard may use its beak to crack them directly. The common call is a repeated hoarse yelping or sharp yap.

Best Time & Places to See It

The black-breasted buzzard is common throughout most of its range, making it a relatively accessible species for wildlife travellers in northern and inland Australia. River Red Gum woodlands in central Australia offer the best opportunities for observation. The species breeds from August to October, with nestlings fledging around December, potentially offering extended viewing opportunities during this period. Look for the buzzard soaring over open woodland and shrubland habitats, or perched conspicuously on exposed branches in tall trees.

Photography Tips

The buzzard's striking plumage makes it highly photogenic. When shooting from below, emphasise the dramatic contrast between the black underparts and white wing panels, which are most visible during flight. The species' long wingspan relative to body size creates distinctive silhouettes—capture these in backlit conditions for maximum impact. The rich mottled red on the back and shoulders is best photographed when the bird is perched or soaring at angles where dorsal plumage is visible. Adults can be individually identified by broken or missing flight feathers, a useful detail for field photography documentation. Patience is rewarded when photographing from vantage points overlooking River Red Gum woodlands, where the birds soar in transects at predictable heights.
