Skilled in terrestrial hunting,[1] the black-breasted buzzard is famous for its use of stones to crack the eggs of large ground-nesting birds such as the Emu (Dromaius novaehollandiae), Brolga (Grus rubicundus) and Australian Bustard (Ardeotis australis). Stones are either dropped onto or thrown at the eggs to break them open, allowing the buzzard to access the contents for food.
