The structure and outer surface body of a bird is easily adopted for flight. Many of the bones of a bide are hollow and dilled with air, making the skeleton extremely light. The bony rigid frame work of a bird’s body is like an aero plane. The neck is long and flexible allowing the bird to direct the vision in any direction. The head being small offers least resistance to air. The birds wing is like an aerofoil. The birds body being convex in the upper portion and concave in the lower portion, allows the air pressure to be decreased to have easy lift
