Definition
A flying bird is any bird capable of flight. These birds possess wings, feathers, lightweight bones, and a keeled sternum (breastbone) for anchoring flight muscles. They use their wings to generate lift and propulsion, allowing them to soar through the air. Flying birds exhibit a wide range of sizes, shapes, and flight styles, from hummingbirds to eagles. Think of them as masters of the aerial realm. They exploit the skies for food, migration, and survival.
