All flying birds have, it's the attachment point for the big breast/chest muscles which they need to be able to fly.
its the sternum.
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.
Chicken Keel is the flexible wedge of cartilage connecting a chickens breast muscles at the tip of the breastbone, not the entire breast.
Flightless birds do not need a large keel because they don't have functional wings for flight, so there is no need for the large breastbone attachment needed for flight muscles. The keel is an adaptation found in birds that use their wings for sustained flight.
A keel has nothing to do with the latitude.A keel does two things:structurally, it acts as the spine(or the breastbone) of the ship to tie the crosswise "ribs" together and provide strength.If the keel is seen on the outside of the hull as a fairly narrow ridge running fore-aft, it'll also help the boat stay on course. This is particularly important for sailing ships, for which the wind will try to push them sideways.Smaller yachts and sailboats can have a fin-like keel sticking straight down instead of a long ridge.Even smaller boats will have a daggerboard doing the same service

Modern Submarines do not have a keel like other ships....
because trumpeter swans' call sounds like a trumpet
The ostrich is a member of the Ratites family, which includes flightless birds characterized by a flat breastbone without a keel.
Yes, heart lies superficially and more like centrally, over the diaphragm.
if the swans put there heads together it looks like a hart.! there is black swans belive it or not. Hope these facts help :)
Yes, Keel-billed Toucans like all Toucans fly.
