The basal part of the wing supplies most of the supporting surface, the wing tip most of the propelling force. WebThe avian skeletal system is notable for its strength and lightness. The number of vertebrae varies from 39 to 63, with remarkable variation within the neck series. The bones of the forelimb are modified for flight with feathers, and wing bones are hollow. The hind toe of the avian foot opposes the other three. toast rolls in air fryer
