“…The humerus of both species was considered one component of the wing skeleton. These findings came in the same line as reported in domestic pigeons [ 9 ], domestic birds [ 10 ], domestic fowl [ 25 ], and crows and owls [ 26 ]. The articulation of the pectoral girdle bones leads to the formation of triosseum foramen as observed in this study and in cattle egrets [ 27 ].…”

“…In pigeons, crows, and owls, the scapula was a blade-like structure and slightly curved from the cranial to the caudal direction [ 26 ]. While in domestic pigeons [ 9 ] the scapula appeared sword in shape with much-reduced acromion, much smaller in relation to body size. In pigeon Hawk and Kite, there was pneumatic foramen just behind the coracoid process of the scapula of the pigeon hawk.…”

“…The important role of the coracoid in holding the wings away from the sternum during the flight was confirmed [ 29 ]. The proximal extremity of the coracoid was hook-like and articulated with the proximal extremity of the scapula and clavicle to form the foramen triosseum [ 9 ] in domestic pigeons. The strong development of supracoracoideus and sternocoracoideus muscles and the more strongly developed coracoid of kite improved their adaptation feature to catch their prey during flight [ 28 ].…”

“…The clavicles were two in number – right and left which were fused distally to form a single bony structure called furcula in pigeons, crows, and owls [ 26 ]. Furcula had different shapes according to the species; domestic pigeons had a broad 'U' shaped furculum with rudimentary hypocleideum [ 9 ]. It was U shaped in crows [ 32 ] and pariah kite [ 33 ] while in fowl the furculum appeared a wide 'V' shape [ 25 ].…”

“…Functionally, the pectoral girdle allows the body to withstand the movements of wing strokes and transfer force to the sternum and provides an extra anchoring surface for the flight muscles [ 8 ]. Moreover, it also provides wings with the strength and range of motion during flight [ 9 ]. Anatomically, the pectoral girdle of birds consists of the scapula, clavicle, and coracoid.…”

Background The purpose of this study was to explore whether domestication could lead to evolutionary changes towards flightlessness in the domestic duck (Anas platyrhynchos domesticus) compared to the cattle egret (Bubulcus ibis) as a nonflying and flying biological model, respectively. Bones of the pectoral girdle (scapula, clavicle, and coracoid) and the foramen triosseum were comparatively assessed using anatomical, radiographic, and 3D computed tomographic (CT) studies. Additionally, the muscles pectoralis and the supracoracoideus were histologically and immunohistochemically assessed. Results Among the differences observed, radiographically, the distance between the paired clavicles was significantly wider (p < 0.05) in the domestic duck (mean ± SD 1.43 ± 0.23 cm) compared with the cattle egret (0.96 ± 0.13 cm). Unlike cattle egrets, there was no connection between the sternum and the hypocladium of furcula in domestic ducks. The scapula, clavicle, coracoid, sternum, and humerus were considerably longer in domestic ducks than in cattle egrets. The foramen triosseum appeared significantly (p < 0.01) wider in domestic ducks (0.7 ± 1.17 cm) compared to cattle egrets (0.49 ± 0.03 cm). Histologically, compared to cattle egrets, the muscle fibers in domestic ducks were loosely connected and contained fewer nuclei and perimysial/endomysial spaces. A higher myoglobin expression was evident in cattle egrets compared with domestic ducks. Conclusions Results of this study indicate that the bones and muscles of the pectoral girdle generally show specific morphological and structural changes reflective of the loss of prerequisites associated with flight behavior in domestic ducks due to domestication effects compared to cattle egrets.

Background Morphometric study of the bony elements of the appendicular skeleton in the ostrich was fully described and identified. The appendicular skeleton included the bones of the pectoral girdle, the wing, the pelvic girdle and the pelvic limb. Results The shoulder girdle of the ostrich included the scapula and coracoid bones. The scapula appeared as a flattened spoon-like structure. The coracoid bone appeared quadrilateral in outline. The mean length of the scapula and coracoid (sternal wing) were 15.00 ± 0.23 and 10.00 ± 0.17 cm, respectively. The wing included the humerus, ulna, radius, radial carpal bone, ulnar carpal bone, carpometacarpus and phalanges of three digits. The mean length of the humerus, radius, and ulna were 33.00 ± 0.46, 10.50 ± 0.40 and 11.50 ± 0.29 cm respectively. The carpometacarpus was formed by the fusion of the distal row of carpal bones and three metacarpal bones. Digits of the wing were three in number; the alular, major and minor digits. Os coxae comprised the ilium, ischium and pubis. Their mean lengths were 36.00 ± 0.82 cm, 32.00 ± 0.20 and 55.00 ± 0.2.9 cm, respectively. The femur was a stout short bone, that appeared shorter than the tibiotarsus. The mean length of the femur, tibiotarsus, and tarsometatarsus were 30.00 ± 0.23, 52.00 ± 0.50 and 46.00 ± 0.28 cm. Tibiotarsus was the longest bone in the pelvic limb. The fibula was a long bone (44.00 ± 0.41 cm) lying along the lateral surface of the tibiotarsus. The tarsometatarsus was a strong long bone formed by the fusion of the metatarsal (II, III, IV) and the distal row of tarsal bones. It was worth mentioning that metatarsal II was externally absent in adults. Conclusions In the appendicular skeleton of ostrich, there were special characteristic features that were detected in our study; the clavicle was absent, the coracoid bone was composed of a sternal wing and scapular wing, the ulna was slightly longer in length than the radius. The coupled patellae i.e., the proximal and distal patella were observed; and the ostrich pedal digits were only two; viz., the third (III) and fourth (IV) digits.
