Alice Springs Desert Park on Instagram: "The Black-breasted buzzard uses its instinctual behaviour to crack and get into Emu eggs when they come across an unprotected nest. Since the eggs are too tough to break with their feet and beaks alone, they use small rocks which they throw at the eggs. Once the eggs are cracked, they can indulge in a protein-packed meal! You can see this behaviour demonstrated almost daily at our free Flying Bird show at the amphitheatre."
