Question

what are the function of keel in birds???

Answer 1

Answer:

In bird anatomy, the Keel is an extension of the breastbone (sternum). The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Not all birds have keels, in particular flightless birds lack a keel structure.

Answer 2

Answer:

A keel or carina (plural carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. ... Without a keel a bird will not be able to fly.
