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.
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 to 60 cm (20–24 in) in length and has a wingspan of 145 to 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
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.
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).
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.
