The keel bone (carina) provides the main attachment for the flight muscles. It is most developed in sophisticated fliers like swifts and hummingbirds and least developed in the flightless ratites, which have a flat and raft-like sternum (Bezuidenhout 1999; King & McLelland 1984; Maina 1996).
Which birds do not have a keel?

Does Carina fly?
CARINA will fly much lower for longer duration than any satellite currently in orbit. Three instruments designed to measure the ionosphere throughout the mission duration are being flown on CARINA.
What’s a Carina?
A ridge at the base of the trachea (windpipe) that separates the openings of the right and left main bronchi (the large air passages that lead from the trachea to the lungs). Also called tracheal carina.
Where are ratites found?

Why do birds have a keeled sternum?
A keel in bird anatomy is an extension of the sternum which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird’s wing muscles attach, thereby providing adequate leverage for flight.
