The skeleton of a dove displays a prominent keel. Its size in relation to the rest of the bird's body gives the dove its characteristic deep-chested appearance.
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 evolutionary studies have shown that many flightless birds have evolved from flighted birds. The current definition of Carinatae now includes all extant birds. In phylogenetic taxonomy, the Carinatae are considered the last common ancestor of Neornithes (living birds) and Ichthyornis (an extinct seabird of the Cretaceous). ... Families Struthionidae Casuariidae Dinornithidae Apterygidae Rheidae A ratite is any of a diverse group of large, flightless birds of Gondwanian origin, most of them now extinct. ... Extant means still existing. It is the opposite of extinct, and can be applied to species, cultures and works of culture (e. ...

Birds who are not allowed to weather without the guard on will develop even more brittle tails as they are prevented from properly preening their tail feathers.
A keel in birdanatomy 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.
