Of all the birds in the world, hummingbirds are the best fliers. One of the things that makes them great fliers is the size of their chest. All birds have two chest muscles, one to raise the wings, and one to lower them. When the first muscle contracts it pulls the wings up. When the other muscle contracts it pulls the wings down. Most birds have small muscles for raising their wings. All their power comes from the downbeat. But hummingbirds have big muscles for raising and lowering their wings. They are the only birds that get flying power from both wingbeats. That is why they are such superb fliers.
Basic : All birds have feathers, beaks/bills, two feet, wings, and lay eggs. More complex: All birds have crops, gizzards, a four chambered heart, and are warm-blooded.
