Macro-anatomy of the Bones of Thoracic Limb in Dalmatian Pelican (Pelecanus crispus)

ABSTRACT In this study, the bones forming the poultry skeleton of the Dalmatian pelican were macroscopically examined. For this purpose, three Dalmatian pelicans were used. In the Dalmatian pelicans, the shoulder girdle (Ossa cinguli membri thoracici) is formed by the scapula, os coracoideum and clavicula bones. The scapula bone was short and flat. The humerus was a long bone with a cylindrical, pneumatic structure. Os corocoideum was also in the processus coracoideus tuber. Radius formed a joint with the ulna, and presented a slight slope from proximal to distal direction. Ossa carpi bones (skeleton manus) were composed of os carpi ulnare and os carpi radiale. The phalanx proximalis digiti majoris had a triangular shape on the dorsal side and two blade-shaped phalanxes. The bones that make up the structure of the Dalmatian pelican’s wing have significant similarities to other birds, but also to have many particular characteristics.
