Abstract:The wing myology of three species of Fringillidae and one of Ploceidae were examined. These species were the Cardinal (Richmondena cardinalis), the White-throated Sparrow (Zonotrichia albicollis), the Song Sparrow (Melospiza melodia), and the English Sparrow (Passer domesticus). In each of the above species 43 muscles directly controlling action of the wing were examined, and the origin and attachment and description of each muscle was noted. The development of each muscle was compared in the above species, and with the musculature as described by other authors of the new world vultures, the woodpeckers, and the Raven. The function of each muscle was likewise compared. The following was noted: The wing myology of the four species examined was essentially similar. The Song Sparrow relatively had the least powerful musculature. The innervations of the shoulder musculature was fundamentally similar in the fringillids. In the fringillids examined the brachial plexus was formed by four spinal nerves. In the one ploceid examined the brachial plexus was formed by three spinal nerves. Compared with birds having soaring or gliding flight, the species examined had a relative increase in size and power of the musculature, particularly of those muscles which are of importance in flapping flight. Compared with birds having soaring or gliding flight, the species examined had a reduction in the number and power of muscles controlling movements of the hands. Thirteen muscles were noted of which the differential development or occurrence might be of taxonomic use.
