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 windy atmosphere. Young (1958) is not upon when he calls the dames as masters of the transmit there is practically no system, or no organ, that has not been modify in relation to escape valve. The following account incisively indicates how much birds be adapted to their lively mode of sprightliness through anatomy, embryology, physiology and ecology. The course spindle shaped bodies of birds is the result of aerial adaptation. The body is knowing in such a way of life that allows a bird to propel through the subscriber line in such a manner, similar to a fish melted in water. A birds light weig ht body is really compact. Dorsally inexpugnable and ventrally heavier body help in maintaining a birds sleep in the air. Feathers argon one of the astounding features of birds which other animal groups do not posses. Backwardly arranged contour feathers make a birds body streamlined and reduces air abrasion during a birds flight.

escaped weighted feathers make a covering 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 sacrifice 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 linear flight feathers of wings are called remiges. This flight feathers form a broad surface for living the birds in air. The upper convexo-concave surface and lower planoconcave surface of wings reduces air pressure above and affix air pressure from below, with marginal turbulence behind. This helps in a birds...If you want to get a full essay, order it on our website: OrderCustomPaper.com
