Birds constitute a well specify group of vertebrate zoologys. As a class they shape a more homogenous group than any other class of vertebrate. Birds can be described as feathered, bipedal, degraded vertebrate who posses wings. Birds posses specific characteristics which allow them to weather and adapt in an aerial atmosphere. Young (1958) is not upon when he calls the dames as masters of the air there is practically no system, or no organ, that has not been modify in relation to flight. The following account precisely indicates how much birds be adapted to their aerial mode of life through anatomy, embryology, physiology and ecology.
The contour spindle shaped bodies of birds is the result of aerial adaptation. The body is knowing in such a way that allows a bird to propel through the air in such a manner, similar to a fish swimming in water. A birds light weight body is very compact. Dorsally inexpugnable and ventrally heavier body help in maintaining a birds sleep in the air.
Feathers argon one of the astonishing features of birds which other animal groups do not posses. Backwardly arranged contour feathers make a birds body streamlined and reduces air friction during a birds flight.



escaped weighted feathers make a blanket 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 have been modified into wings. These marvelous modified forelimbs (wings) are equipped with flight muscles that have been developed as instruments of propulsion through air. The elongated flight feathers of wings are called remiges. This flight feathers form a broad surface for living the birds in air. The upper convex surface and lower planoconcave surface of wings reduces air pressure above and affix air pressure from below, with minimum turbulence behind. This helps in a birds...If you want to get a full essay, order it on our website: Orderessay
