Explanation:

Ask any elementary school student why birds have hollow bones and they'll have an easy answer for you: It's to help them fly! Gold star, kid. But how do hollow bones really help birds fly? Contrary to popular belief, it's not because it makes them lighter. It's because they need so much oxygen to fly that their lungs actually extend into their bones.
