The wishbone or furcula is the fusion of a bird's two collarbones (clavicles) into a single structure. The furcula works as a strut between a bird's shoulders, and articulates to each of the bird's scapulae.In conjunction with the coracoid and the scapula, it forms a unique structure called the triosseal canal, which houses a strong tendon that connects the supracoracoideus muscles to the humerus.This system is responsible for lifting the wings during the recovery stroke.
