Intermediate in body size between the well-known larger wedge-tailed eagle (Aquila audax) and the smaller little eagle (Hieraaetus morphnoides), the black-breasted buzzard is one of Australia's largest birds of prey. An adult buzzard measures 51–61 cm in height including its short square tail. The buzzard's outstretched wingspan measures 147–156 cm, rendering the bird distinctive in flight as its wings are conspicuously long relative to its stout body and tail. Buzzards appear sexually monomorphic (identical in physical appearance), although the adult female is slightly larger, weighing approximately 1330 g compared to the 1196 g of the adult male. It is most closely related to the Square-tailed kite (Lophoictinia isura). Learn more about Black-Breasted Buzzard
