This stylised bird skeleton highlights the synsacrum Pelvis of a Gull; formed by the Synsacrum (fused vertebrae placed centrally) and the two innominate bones either side The synsacrum is a skeletal structure of birds [ 1 ] and other dinosaurs , [ 2 ] pterosaurs, [ 3 ] as well as xenarthran mammals, [ 4 ] in which the sacrum is extended by ...
Swimming birds have a wide sternum, walking birds have a long sternum, and flying birds have a sternum that is nearly equal in width and height. [19] The chest consists of the furcula (wishbone) and coracoid (collar bone) which, together with the scapula , form the pectoral girdle ; the side of the chest is formed by the ribs, which meet at the ...

In Classical Greek the bone was known as κλόνις (Latinized clonis); this term is cognate to Latin clunis "buttock", Sanskrit śróṇis "haunch" and Lithuanian šlaunis "hip, thigh". [ 26 ] [ 27 ] The Latin word is found in the alternative Latin name of the sacrum, ossa clunium , as it were "bones of the buttocks". [ 20 ]
The furcula (Latin for "little fork"; pl.: furculae) [a] or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles. [1] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet).
Carpometacarpus is in red in this description of the bird wing bones. To non-biologists the carpometacarpus may be best known from buffalo wings. Buffalo wings come in two basic sizes, a large angled one containing three major bones, and a smaller flat one containing only two. The bone missing in the latter is the carpometacarpus.
Traditionally, Carinatae were defined as all birds whose sternum (breast bone) has a keel (carina). The keel is a strong median ridge running down the length of the sternum. This is an important area for the attachment of flight muscles. Thus, all flying birds have a pronounced keel. Ratites, all of which are flightless, lack a strong keel.
