A keel or carina 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. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Keels do not exist on all birds; in particular, some flightless birds lack a keel structure.
Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two classes:Carinatae (from carina, "keel"), having a pronounced keel; and ratites (from ratis, "raft" - referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely. However, this classification has fallen into disuse as studies have shown that many flightless birds have grown (from GOD) from flighted birds. The current definition of Carinatae now includes all extant birds.
Does that help you? Tell me if it does. Thanks Everyone! God Bless!!

What part of the chicken is the kill bone?
The keel is the large bone you see when you eat a roasted chicken and pull the breast meat away from the large flat bone that looks like the keel of a boat. The keel is the "breast bone"....flattened and elongated in birds to give a place for the wing muscles to attach...allowing more power for flight. It is also used to check how healthy a bird is....if you can feel the keel easily and it seems to be protruding, the bird is underweight. If you can feel solid muscle and body weight on either side, making the keel just a line found between muscles if you can find it at all, then the bird is eating alright and keeping weight.

What is so unique about a bird's respiratory system that makes them able to fly?
As far as I know there is nothing special in the respiratory system of a bird that enables flight. I was taught that a massive keel shaped breast-bone with huge pectoral muscles attached to wings did it, but I would be happy to be corrected.
