The following account precisely indicates how much birds be adapted to their f lookylike mode of deportment through anatomy, embryology, physiology and ecology. The limn spindle shaped bodies of birds is the result of aerial adaptation. The body is knowing in such a centering that allows a bird to propel through the air in such a manner, similar to a fish fluent in water. A birds light weight body is ver y(prenominal) compact.

escaped weighted feathers make a chimneypiece like natural covering around body and helps in providing buoyancy. Non conducting properties of feathers prevent birds from harsh climatical changes from high altitude flight. (Feathers, n.d.) Forelimbs excite been modified into wings. These m arvelous modified forelimbs (wings) are equi! pped with flight muscles that have been developed as instruments of propulsion through air. The extended flight feathers of wings are called remiges. This flight feathers form a broad surface for living the birds in air. The upper gibbous surface and lower planoconcave surface of wings reduces air pressure above and affix air pressure from below, with borderline turbulence behind.
