Aerodynamic drag is the force opposite to the direction of motion and hence the source of energy loss in flight The drag force can be separated into two portions lift induced drag which is the inherent cost of the wing producing lift this energy ends up primarily in the wingtip vortices and parasitic drag including skin friction drag from the friction of air and body surfaces and form drag from the bird s frontal area The streamlining of bird s body and wings reduces these forces.
Beneath the pectoralis major lies the supracoracoideus the breast muscle that powers the upstroke It is the muscle immediately over the breast bone The tendon of this muscle passes through the triossial canal an opening between the coracoid humerus and furcula and inserts into the humerus When the supracoracoideus contracts the tendon pulls the humerus and consequently the rest of the wing upward The unsual arrangement of this muscle keeps it below the center of gravity helping to stabilize flight
