It anchors down the bird's flight muscles.
THE KEEL OF A BIRD IS NONE OF YOUR BEEZWAX! NOW GET OUT OF MY BUISSNES YOU FREAK! :z
The keel billed toucan groups together with other birds and scare off the predator. Many birds together scare the bird
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!!
They do not need to flap their wings.

On a ship or boat, the keel is the main structure along the bottom on which the rest of the frame is built. It could also mean when a boat keels (capsizes) over. It could also be the ridge on the front of a birds' breastbone.
It makes Keel which is boat shaped that reduces friction in flight and flight muscles are attached to it.
All flying birds have, it's the attachment point for the big breast/chest muscles which they need to be able to fly.
