Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Black-breasted Buzzard

The black-breasted buzzard (Hamirostra melanosternon) or black-breasted kite, is a large bird of prey in the family Accipitridae and the monotypic genus Hamirostra. It is sometimes known as the black-breasted kite, but is neither a kite nor a buzzard, rather a kind of eagle.

Description[edit]

The black-breasted buzzard is a large bird of prey, intermediate in size between the little eagle and the wedge-tailed eagle. It is 50–60 cm (20–24 in) in length and has a wingspan of 145–155 cm (57–61 in). Females are larger than the males, and weigh more, with males weighing around 1.2 kg (2.6 lb) and females weighing 1.4 kg (3.1 lb). Adult birds are relatively easy to recognise by their mainly dark plumage combined with distinctive white patches on the wings at the bases of the primary feathers.

Distribution and habitat[edit]

Native to Australia, the black-breasted buzzard is found mainly in the northern and central parts of the continent, living in the deserts, dry grasslands, shrublands, sparse tropical woodlands and tree-lined watercourses. It does not occur in Tasmania.

Feeding[edit]

Black-breasted buzzards eat rabbits, large lizards, other birds and carrion. It will also raid the nests of ground-nesting birds, breaking large eggs by hurling stones against them with its large beak and then eating the contents. (see gallery below).

Breeding[edit]

This species nests in trees, often along watercourses, building a platform of sticks with a central leaf-lined depression for the clutch of usually two eggs. The incubation period is about 40 days, with chicks fledging about 60 days after hatching.
